I remember the first time I tried to swap out the polymer grip on my WASR-10. Looked simple enough. Grabbed a new grip, saw the single screw holding the old one on, and figured any old screw would do if I lost it. Spoiler alert: they don’t. That little oversight led to a frustrating afternoon and a nearly stripped receiver. It really hammered home the point: even seemingly minor parts matter. So, to get straight to the point, are all AK47 grip screws the same length? It’s a good question, and the answer is usually ‘yes,’ but with enough ‘buts’ to make you want to check your specific rifle.
This isn’t some high-tech component where manufacturers get wild with tolerances. For the most part, these things are pretty standardized. But if you’re building, repairing, or just upgrading, ignoring the specifics can turn a quick job into a headache. Let’s cut through the noise and talk about what you actually need to know.
Why Ak Grip Screw Length Matters (more Than You Think)
Look, nobody gets excited about a grip screw. It’s buried under the grip, it’s just a piece of metal, right? Wrong. This tiny piece of hardware is the anchor for something you hold onto constantly.
If it’s too long, it can bottom out, potentially damaging the receiver or the grip itself. Too short, and you won’t get enough purchase, leading to a wobbly grip or, worse, the screw stripping out. I learned this the hard way trying to fit a aftermarket grip that came with what I thought was a standard screw.
It was about 3mm too long. I kept turning, thinking it just needed a bit of force, and ended up with a slight deformation on the inside of my receiver’s magazine well. It wasn’t catastrophic, but it was a mess I had to deal with. That cost me time and a little bit of my sanity.
The common advice you’ll find online is that most AKM and AK-74 pattern rifles use the same length grip screw. And for the most part, that’s true. We’re talking about a pretty established platform, and standardization for common parts like this makes sense from a manufacturing standpoint. Think about it: why would a factory make a different length screw for every single AK variant if a single length works for 95% of them? It’s just not economical. The vast majority of screws you buy specifically labeled for AK grips will be around 20mm to 25mm in length. This range covers most stamped receivers.
However, ‘most’ is the operative word here. There are nuances. Some older or less common variants, or rifles that have had modifications or non-standard receivers fitted, might require a different length. For instance, some milled receivers, especially those from different countries or older production runs, might have slightly different depths or internal geometries. It’s rare, but it happens. The biggest variables are often the grip itself and any aftermarket furniture you’re fitting. Some pistol grips are thicker than others, and this thickness can change how much of the screw is engaged. So, while the receiver might be standard, the grip can throw a wrench into the works.
If you’re buying a new grip, it’s always best to see if it comes with its own screw. Reputable manufacturers will include the correct hardware or at least specify what you need. If you’re sourcing parts separately, especially from surplus or mixed lots, that’s when you need to be extra careful. A quick measurement of your existing screw, or a peek inside the receiver if possible, is worth the few minutes it takes. It’s the difference between a five-minute swap and a frustrating Saturday afternoon spent hunting for the right fastener.
The Standard Ak Grip Screw: What You’re Likely Dealing With
Okay, let’s talk brass tacks. When people ask if all AK47 grip screws are the same length, they’re usually thinking about the vast majority of AK-pattern rifles out there – the AKM, the AK-74, and their common derivatives. For these, the standard length is typically in the neighborhood of 20mm to 25mm. This is a metric thread, usually an M6 size, which is pretty common for many firearm applications. The head is typically a socket or Allen head, designed to be tightened with a hex wrench. The goal is a snug fit that holds the grip securely without over-penetrating the receiver or stripping out.
Why this specific range? It’s a balance. The screw needs to be long enough to get a good bite into the threaded hole on the receiver. This hole is usually part of a steel insert or directly threaded into the receiver itself, depending on the model and manufacturer. The internal depth of this threaded hole dictates the maximum length of the screw you can use without causing issues. A screw that’s too long will bottom out, potentially stretching the threads, cracking the insert, or even deforming the surrounding metal of the receiver. That’s a bad day, potentially a very expensive one.
I’ve seen a few instances where people try to use screws from other platforms, or even generic hardware store screws. Big mistake. While you might find an M6 screw at the hardware store, the thread pitch and overall dimensions might not be exactly right, and the material strength might be lower.
Even a few millimeters can make a difference. For example, I had a buddy who was building an AK pistol and ran into a problem. He bought a grip, and the screw it came with was just a hair too short.
He didn’t think much of it, but the grip felt a bit loose. He ended up using a slightly longer screw he found lying around. Turns out, that slightly longer screw was actually a metric fine-thread that looked similar but was slightly different. It worked for a while, but eventually, it started to back out under recoil.

A lost grip screw during a range session is more than just an inconvenience; it can be a safety hazard.
The best bet for most common AKs is to buy a screw specifically marketed for AK grips. These are usually readily available from online retailers specializing in firearm parts. They’ll typically be listed as M6x20mm or M6x25mm, and often come with a corresponding washer, which is also important for making sure even pressure and preventing damage to the grip base.
| Common AK Grip Screw Lengths (Approximate) | Verdict |
|---|---|
| 20mm – 25mm | Standard for most AKM/AK-74 stamped receivers. This is what you’ll find 90% of the time. |
| Shorter (e.g., 15mm) | Rare, but might be found on some very specific, older, or non-standard builds. Check receiver depth. |
| Longer (e.g., 30mm+) | Almost certainly incorrect for a standard AK receiver. Likely to cause damage. |
When ‘same Length’ Doesn’t Cut It: Variations and Exceptions
Here’s where things get a little murky, and it’s why the simple ‘yes’ answer to are all AK47 grip screws the same length is often followed by a sigh. While the standard is indeed common, we need to talk about the outliers.
First off, not all AKs are built on the same receiver type. You’ve got stamped receivers, which are the most common on AKMs and AK-74s.
Then you have milled receivers, often found on older variants like the AK-47 itself, some Yugoslavian models (like the M70), and certain modern builds or premium AKs. Milled receivers can sometimes have a slightly different internal depth or shape where the grip screw threads in. This isn’t a universal rule, but it’s a factor.
Then there’s the grip itself. Aftermarket pistol grips vary wildly in thickness and design. Some are slim and ergonomic, designed to fit flush with the receiver. Others are chunkier, offering more storage space or a different feel. A thicker grip will require a longer screw to achieve the same amount of thread engagement as a slimmer grip on the same rifle. Conversely, a very thin grip might make a standard-length screw seem too long, potentially causing it to bottom out prematurely. This is why many aftermarket grip manufacturers will either include their own proprietary screw or provide specific guidance on the length needed.
I’ve personally run into this when fitting a Bulgarian-style polymer pistol grip onto a Romanian WASR. The original grip screw was fine. When I got the new grip, it was a bit thicker at the base. The screw that came with the new grip was about 5mm longer than the original. I almost didn’t use it, thinking it looked too long. But fitting it, I realized it was the only way to get a solid thread engagement. If I had used the shorter, original screw, the grip would have been loose and wobbly. It’s a direct consequence of the grip’s geometry changing the effective depth.
Another area of variation can be receivers that have been modified. Sometimes, internal components are altered, or custom trigger guards are fitted, which can subtly change the available space for the grip screw. It’s rare, but if you’re dealing with a heavily modified rifle or a Frankenstein build, you can’t just assume. Finally, let’s not forget about different countries of origin. While Soviet/Russian designs are the baseline, AKs have been produced all over the world, and minor variations in manufacturing, even for seemingly identical parts, can creep in. So, while 20-25mm is your go-to, always be prepared to measure or verify if you’re working with something less common or heavily customized.
People Also Ask:
Do Ak Grips Need a Washer?
Yes, most AK grips benefit from a washer. The washer distributes the pressure from the screw head over a larger area of the grip’s base, preventing the screw from digging into or damaging the polymer or wood. It also helps make sure consistent torque and can prevent the screw from backing out under vibration and recoil. A properly sized washer is a small but important detail for a secure grip installation.
DIY Solutions and Common Mistakes When Replacing Ak Grip Screws
So you’ve lost your AK grip screw, or the one you have is stripped, and you need a replacement. What are your options, and what should you absolutely avoid? First, the best and most reliable option is to buy a purpose-made AK grip screw from a reputable firearms parts vendor. These are typically M6 threaded fasteners, around 20-25mm in length, and made from hardened steel. They’re designed to withstand the forces involved and thread properly into the receiver. They’ll often come with a washer too. This is the path of least resistance and highest certainty. Expect to pay anywhere from $3 to $10 for a good quality replacement screw and washer set.
Now, for the DIYer who finds themselves in a bind, there are potential workarounds, but tread carefully. If you have another AK or a similar firearm, you might be able to temporarily borrow a screw. Measure it first, though!
As we’ve discussed, length is key. If you’re at a hardware store, looking for an M6 screw, remember that thread pitch is just as important as length. (See Also: Are Black Screws Rust Resistant )
An M6x1.0 (standard metric thread) is what you’re usually looking for. Do NOT grab an M6x0.75 (fine thread) or anything else that looks “close.”
Using the wrong thread pitch can damage the threads in your receiver, which is a much bigger problem to fix. Also, make sure it’s made of steel and has a decent hardness rating; you don’t want a screw that deforms easily.
The biggest mistake I see people make, apart from using the wrong thread pitch, is overtightening. This is especially true if they have a screw that’s a little too long. They keep turning, trying to get the grip snug, and end up stripping the threads in the receiver or the screw itself.
Remember, the goal is a secure grip, not to compress the receiver into submission. Once the screw stops turning with reasonable hand-tight effort and a final snugging with a wrench (don’t go crazy!), stop. A little bit of thread locker (like Loctite Blue) can be a good idea for extra security, especially if you’ve had issues with screws backing out in the past.
Just a tiny drop is all you need.
Another common pitfall is reusing a damaged screw. If the head is stripped, or the threads look chewed up, toss it and get a new one. Trying to force a damaged screw is a recipe for disaster. Lastly, if your receiver’s grip screw hole is already damaged or stripped, a simple screw replacement won’t fix it. You’ll need to consider thread repair inserts or professional gunsmithing. That’s a whole other can of worms, but it underscores the importance of using the correct screw and torquing it properly in the first place. My own little mishap with the slightly-too-long screw taught me that even minor screw length differences can have consequences if not handled with care.
The Pragmatic Guide to Buying the Right Ak Grip Screw
Let’s cut to the chase. You need a grip screw for your AK. Where do you go, and what should you look for? The first place to check is the manufacturer of your specific rifle or the manufacturer of the aftermarket grip you’re using. Many rifle manufacturers, like Century Arms for WASRs or PSA for their AK line, sell spare parts directly. If you bought a fancy new grip from Magpul, Hogue, or another well-known brand, their website or product listing will usually specify the correct screw size or include one. This is your safest bet.
If you can’t get info from the source, the next best option is a reputable online retailer specializing in AK parts. Think sites like AK-Builder, K-Var, or other dedicated AK parts suppliers. Search for ‘AK grip screw’ or ‘AKM grip screw.’ You’ll likely see options that are M6x20mm or M6x25mm. These are your standard sizes for stamped receivers. They’ll usually be made of steel, often black oxide finished, and might come with a washer. Prices will vary, but expect to spend around $5-$15 for a quality screw and washer.
When you buy, look for descriptions that mention ‘stamped receiver’ or ‘AKM/AK-74 pattern.’ If you have a milled receiver, it’s worth doing a quick search specific to your rifle model (e.g., ‘M70 grip screw length’) or, ideally, measuring the depth of the threaded hole on your receiver if possible. You can use a small pick or even a wooden skewer to gauge the depth. Just push it in until it stops, mark the depth with your finger, and then measure the inserted portion. Compare that to common screw lengths. A screw that is about 2-3mm shorter than the measured depth is usually ideal to avoid bottoming out.
My Personal Experience With Grip Screws: A Quick Table
| Rifle/Grip | Screw Length Used | Result |
|---|---|---|
| WASR-10 (Standard Grip) | 22mm | Perfectly secure, no issues. |
| AKM Clone (Aftermarket Polymer Grip, Thicker) | 25mm | Needed the extra length for proper thread engagement. Rock solid. |
| ‘Franken-AK’ Build (Unknown Receiver) | Tried 20mm, then 23mm | 23mm was the sweet spot. 20mm was too short for a stable grip. |
Don’t shy away from a washer. It’s a simple component, but it makes a difference in how evenly the pressure is applied and can prevent damage to your grip. If a screw comes with a washer, use it. If you buy a screw separately, consider getting a matching washer. It’s usually a standard M6 flat washer. For most folks, sticking to the 20-25mm range for stamped receivers and buying from a reputable source will solve the problem. It’s the most straightforward way to make sure you’re not introducing problems with a simple part.
Can You Use a Different Type of Screw? (spoiler: Don’t)
Let’s address a question that might pop into some minds: Can I just use a different type of screw, like a bolt, or something from my junk drawer? The short answer is: probably not, and you really shouldn’t. The people asking if are all AK47 grip screws the same length are usually trying to be practical, and sometimes that practicality leads down a dangerous path. Firearms are precise instruments, and while the AK is known for its ruggedness, that doesn’t mean you can just swap parts willy-nilly without understanding the consequences. (See Also: Are Blue Concrete Screws Waterproof )
The screw used for an AK grip isn’t just any old fastener. It’s a specific metric thread (usually M6) with a particular length (typically 20-25mm) and thread pitch (usually 1.0mm). It’s made of hardened steel to withstand the forces of being tightened and the vibrations of recoil. Using a screw with the wrong thread pitch is a guaranteed way to damage the threads in your receiver.
Imagine trying to screw in a bolt with the wrong size threads – it either won’t go in, or it grinds and strips the threads. Doing that to your firearm’s receiver is a costly repair, often requiring specialized tools or inserts. I heard from a guy once who tried to force a slightly-off screw, and he ended up needing to have a gunsmith re-thread the entire receiver hole. That’s not a cheap fix.
Even if you find a screw that looks like it fits and has the right thread pitch, its material strength might be insufficient. A lower-grade steel screw could strip under normal torque, or worse, deform over time with recoil, leading to a loose grip. A loose grip isn’t just annoying; it can affect handling and, in extreme cases, potentially cause issues with other components if it shifts or comes detached. I once had a cheap, non-firearm-specific screw start to fray its head after only a few dozen rounds. It looked like it was about to give way entirely. Swapping it out for a proper AK grip screw was a relief.
The head type is also a consideration. Most AK grip screws use a hex (Allen) head, which allows for good torque application without slipping. If you use a screw with a slot head or a different type of drive, you might not be able to get it tight enough, or you risk damaging the head.
Ultimately, the small cost of a proper AK grip screw – usually just a few dollars – is insignificant compared to the potential damage and hassle of using an incorrect fastener. Stick to parts specifically designed for AKs.
According to the Kalashnikov Concern’s general design principles, parts interchangeability and standardization within specific platforms are key for reliability and ease of maintenance, and grip screws are no exception to this rule of thumb for common variants.
Frequently Asked Questions About Ak Grip Screws
What Is the Standard Thread Size for an Ak47 Grip Screw?
The standard thread size for most AK47 and AKM pattern rifles is M6, meaning a 6mm diameter screw. The thread pitch is typically 1.0mm, which is a standard metric thread. Always verify if possible, as non-standard or heavily modified rifles can sometimes deviate.
How Long Should an Ak Grip Screw Be?
For most stamped receiver AKM and AK-74 pattern rifles, a length of 20mm to 25mm is standard. This length makes sure sufficient thread engagement without bottoming out in the receiver. Thicker aftermarket grips might require the longer end of this range, or even slightly more, while very thin grips might need a shorter screw.
Can I Use a Screw From Another Rifle?
It’s generally not recommended unless you are absolutely certain it’s the same thread size, pitch, and length. Differences in even a millimeter can cause damage or an insecure fit. It’s best to use screws specifically made for AK grips or confirmed to be compatible with your rifle’s receiver.
What Happens If My Ak Grip Screw Is Too Long?
If an AK grip screw is too long, it will bottom out inside the receiver before the grip is fully seated. This can damage the threads of the receiver or the screw, potentially crack the receiver’s threaded insert, or even deform the surrounding metal. It can also prevent the grip from tightening properly, leading to a loose fit.
Where Can I Buy an Ak Grip Screw?
You can buy AK grip screws from online firearms parts retailers, specialized AK part suppliers, and sometimes directly from the manufacturer of your rifle or aftermarket grip. Make sure the seller specifies compatibility with common AK platforms.
Final Verdict
So, to circle back, are all AK47 grip screws the same length? For the overwhelming majority of common AK platforms out there, especially stamped AKM and AK-74 variants, they are indeed very similar, typically falling within that 20-25mm range. It’s a testament to the AK’s solid and fairly standardized design for its most prevalent iterations. However, as we’ve seen, assuming this can lead you astray if you’re working with a milled receiver, a particularly thick aftermarket grip, or a rifle that’s seen some non-standard modifications over the years.
The real takeaway here is to treat this small part with the respect it deserves. Don’t just grab any old screw. If you’re buying a new grip, check if it comes with hardware. If not, or if you’re replacing a lost screw, seek out parts specifically labeled for AKs. Measure if you can, and err on the side of caution. A few extra minutes spent verifying the correct length and thread pitch can save you a lot of headaches, damaged parts, and money down the line.
Next time you’re working on your AK, take a moment to appreciate that little screw. It’s the unsung hero keeping your grip solid. And if you’re in doubt, a quick online search for your specific rifle model and ‘grip screw’ will usually get you pointed in the right direction. Stay safe and build smart.
