Do Harddrives Come with Screws?

I remember the first time I had to swap out a hard drive. It was years ago, in a clunky beige tower that sounded like a small jet engine taking off. I’d bought the new drive, all shiny and promising terabytes of glorious space, and then I hit a wall. Screws. Where the heck were the tiny little screws that were supposed to hold this new piece of tech in place?

It’s a question many people run into when they’re upgrading or building a PC: do harddrives come with screws?

The short answer? Usually, no. And that’s a frustrating little detail that trips up a lot of folks.

Why Screws Are the Unsung Heroes (and Usually Not Included)

Look, nobody wants to be in the middle of a computer upgrade, covered in a fine layer of dust bunnies, only to realize they’re missing a handful of tiny, specialized screws. It’s the digital equivalent of starting to build IKEA furniture and finding out there aren’t any dowels. Infuriating.

So, do harddrives come with screws? The honest, no-frills answer is: typically, no. The manufacturers of hard drives—whether they’re spinning magnetic disks (HDDs) or solid-state marvels (SSDs)—focus on making the drive itself. They figure you’re either installing it into a new case that has all the necessary mounting hardware, or you’re replacing an old drive and can reuse the screws from that. It’s a cost-saving measure, plain and simple. Why include something they assume you already have or will get with your computer case?

This is where the common advice, “just reuse the old screws,” comes into play. And sometimes, that works. But other times, the old screws are stripped, lost, or the new drive has slightly different mounting points, especially with the slimmer 2.5-inch drives often found in laptops or smaller form-factor desktops. Those little M.2 NVMe SSDs? They use even tinier screws, often a specific thread size, and if you lose that one, finding a replacement can be a real pain. I’ve definitely spent more time than I’d like hunting for a specific screw in my “bits and bobs” drawer after a hasty drive swap. It’s a lesson learned the hard way: don’t assume the screws will magically appear.

The computer case you’re installing the drive into is usually the real source of these mounting screws. Most decent PC cases come with a small bag of assorted screws, standoffs, and zip ties. This bag is your treasure chest for drive installation. You’ll often find different types of screws: some for mounting the drive itself to a bracket or bay, and others for securing that bracket to the case. The key is knowing which is which.

The Great Screw Hunt: What to Look For

Alright, so if the drive doesn’t come with them, where do you find these elusive fasteners? Primarily, your computer case is the main source. When you buy a new PC case, it’s almost always accompanied by a little plastic bag filled with all sorts of hardware. This bag is your best friend when it comes to installing storage devices, motherboards, power supplies, and expansion cards. You’ll want to rummage through this bag and identify the screws that are appropriate for mounting your hard drive.

For traditional 3.5-inch desktop HDDs, you’re typically looking for a specific thread size. These are often referred to as “UNC threads,” specifically 6-32 UNC. They’re a bit chunkier than the screws used for smaller components. You’ll usually need about four of them to secure the drive to its bay or a mounting bracket. If you’re installing a 2.5-inch SSD (the ones that look like a thin paperback book), they often use the same 6-32 UNC thread, but sometimes a slightly smaller thread like 4-40 UNC might be present, especially in laptop drive bays or specific mounting brackets designed for them. Always visually compare the thread pitch and diameter. (See Also: Do Deck Mate Screws Need A Pilot Hole )

Then there are the M.2 NVMe SSDs. These are the tiny sticks that plug directly into the motherboard. They use a very small screw, often a M2 x 3mm or M2 x 4mm size.

These are incredibly easy to lose. They’re usually black and come with a tiny standoff that attaches to the motherboard first.

The screw then goes through the M.2 drive and into the standoff. If your motherboard didn’t come with one of these screws, or you lost it, it can be a bit of a scavenger hunt. Some motherboards include spares in their hardware bag, but not all. This is where dedicated SSD mounting screw kits can be a lifesaver, though they feel like an unnecessary extra purchase.

Tip: Keep that hardware bag from your case somewhere safe and labeled. It’s a one-stop shop for most of your internal component mounting needs. If you’ve long since lost it, don’t despair. Basic screw sets for PC building are readily available online and at electronics stores.

Common Mistakes and Why They Happen

The biggest mistake, hands down, is assuming the drive comes with screws. I’ve seen it happen to friends and I’ve done it myself when I was younger and less experienced. You get the drive, you open the box, you see the drive, you see the SATA cable (sometimes), maybe a little manual, but no bag of screws. Then comes the frantic search and the muttered curses.

Another common error is using the wrong type of screw. PC cases come with a variety of screws for different purposes. You might have screws for mounting the motherboard, screws for the power supply, and screws for drives. If you grab a motherboard screw (which is often a finer thread and longer) and try to force it into a drive bay, you can strip the threads on both the screw and the bay. This makes for a loose drive or a completely unusable mounting point. It’s not worth the five seconds saved by not checking.

People also sometimes forget about the specific needs of different drive types. While a 3.5-inch HDD might be forgiving with a slightly different screw if it’s just resting in a caddy, a 2.5-inch SSD or an M.2 drive needs to be securely fastened. A loose M.2 drive can actually get damaged from vibration or physical stress. I had a friend whose M.2 SSD was barely hanging on because the screw fell out, and it would randomly disconnect, causing system crashes. It took us ages to figure out it was a loose drive.

Forcing screws is another big no-no. If a screw isn’t going in easily, stop. Back it out, check the alignment, and make sure you’re using the correct screw. You don’t want to be the person who cracked a hard drive casing or stripped out the screw hole in the drive itself. That’s a one-way ticket to needing a new drive, not just new screws.

When Things Go Wrong: Real-World Scenarios

I once helped a buddy build his first PC. He’d saved up for months, got all the components, and was super excited. We got to installing the Samsung 970 EVO Plus M.2 SSD. He’d bought a fancy new case, but in his haste, he’d tossed the hardware bag somewhere. No big deal, right? We found the motherboard, plugged it in, and then realized there was no tiny M.2 screw. The motherboard manual showed where it should go, and the M.2 drive just sort of sat there loosely.

We spent the next hour tearing his room apart, looking for that one tiny screw. We checked the old computer he was replacing, his junk drawer, even the vacuum cleaner bag (don’t ask). Eventually, I found a tiny screw from an old eyeglasses repair kit that just happened to have the right thread. It was a Hail Mary that paid off, but it was a tense hour. That M.2 drive is still in there, working fine, but I swear it still makes me sweat a little thinking about how close we were to disaster.

Another time, I was upgrading my NAS (Network Attached Storage) with larger drives. The NAS unit had specific caddies for each drive, and they came with their own set of screws. The new drives, however, had slightly different screw hole placements on their undersides. It wasn’t a huge difference, but enough that the original screws wouldn’t thread properly. I had to order a specialized drive screw kit online, which felt like a ridiculous expense for a few bits of metal. It was a stark reminder that sometimes, even if you have screws, they might not be the right screws for the job.

This is why I always advocate for having a small, well-stocked “PC hardware drawer” or box. It doesn’t need to be fancy – just a collection of common screws, standoffs, zip ties, and cable management clips. It saves you so much hassle down the line. I’ve got a small Plano tackle box with different compartments, and it’s been worth its weight in gold. It beats emergency runs to the hardware store or frantic online orders for a single screw.

Alternatives and How to Get Them

So, you’ve realized your shiny new hard drive isn’t accompanied by a tiny bag of screws, and your case’s hardware bag is either missing or suspiciously lacking. What now? Don’t panic. You have a few solid options, ranging from free to a few bucks.

1. Scavenge from Old Components: This is the most common and often free method. If you’re replacing an old hard drive, carefully remove its mounting screws. If those screws are in good condition and the right type, they’ll work perfectly for your new drive. Likewise, check any old optical drives, floppy drives (if you’re really old school!), or even old graphics cards that you’re no longer using. Sometimes, components come with their own dedicated mounting screws. Just make sure they’re the right thread size and length – you don’t want them sticking out too far or not gripping enough.

2. Check Your Motherboard Manual/Hardware Bag: While the drive doesn’t come with screws, the motherboard does. Specifically, M.2 SSDs are almost always mounted directly to the motherboard, and the necessary screw and standoff are usually included with the motherboard’s accessory kit. If you’re installing an M.2 drive, this is the first place you should look.

3. Buy a PC Screw Kit: These are widely available online (Amazon, Newegg) and at most computer or electronics stores. They’re usually inexpensive, costing anywhere from $10 to $25. These kits contain a variety of common PC screws, including those for hard drives, motherboards, power supplies, and case panels. They’re a fantastic investment for anyone who builds or upgrades computers regularly. You’ll have the right screw for almost any situation. (See Also: Does Showing Screw Driver Into The Ignition )

4. Visit a Local Computer Shop or Electronics Repair Store: If you need just one or two specific screws in a pinch, a good local shop might be willing to sell you a small handful or even give you a couple if they have spares lying around. It’s worth a shot before ordering a whole kit if you’re in a hurry.

5. The Eyeglasses Repair Kit Trick (for M.2): As I mentioned in my anecdote, sometimes a tiny screw from an eyeglasses repair kit can be a lifesaver for M.2 drives. These screws are incredibly small and often have a Phillips head. While not ideal for long-term stability in all cases, it can get you up and running if you’re desperate. Just be aware that the thread might not be an exact match, and it’s a temporary fix at best.

Faqs About Hard Drive Screws

Do Ssds Come with Screws?

Generally, no. Just like traditional HDDs, SSD manufacturers typically do not include mounting screws with their drives. You’ll need to source these from your computer case’s hardware kit, from old components, or purchase a dedicated PC screw set.

What Size Screws Do Hard Drives Use?

For standard 3.5-inch desktop HDDs, the most common screw size is 6-32 UNC. For 2.5-inch SSDs, it’s often the same 6-32 UNC, but sometimes a smaller 4-40 UNC thread is used, especially in laptop drive bays or specific enclosures. M.2 NVMe SSDs use very small, specific screws, typically designated as M2 size (e.g., M2 x 3mm or M2 x 4mm).

Can I Reuse Screws From an Old Hard Drive?

Yes, you often can, provided they are the correct size and thread type for your new drive and the mounting location. Make sure the old screws are not stripped or damaged. Visually compare them to the mounting holes on the new drive and in the bay to confirm compatibility before attempting to install.

What If I Can’t Find the Screws for My M.2 SSD?

The screw for an M.2 SSD is typically provided with your motherboard, not the SSD itself. Check the small bag of accessories that came with your motherboard. If you’ve lost it, you can purchase small M.2 mounting screw kits online, or sometimes a very small screw from an electronics repair kit might work as a temporary solution.

Where Can I Buy Replacement Hard Drive Screws?

You can buy replacement hard drive screws from online retailers like Amazon or Newegg, or at local computer stores and electronics retailers. Buying a general PC hardware screw kit is often the most cost-effective way to make sure you have the right screws for various components.

Verdict

So, to finally put this to bed: do harddrives come with screws? Almost universally, no. It’s one of those annoying little truths in the PC building world that catches people out. You’re usually expected to get them from your computer case’s hardware bag, or reuse them from an old drive. For M.2 drives, the screw typically comes with the motherboard.

My advice? Before you even open that new drive box, locate your computer case’s original hardware bag. If you can’t find it, a cheap PC screw kit is a ridiculously good investment. It’ll save you time, frustration, and potentially a damaged component down the line. Don’t be that person scrambling for screws at 10 PM.

Next time you’re upgrading, do yourself a favor and do a quick screw inventory before you start. It’s a small step that makes a big difference.
