I remember the first time I cracked open an iPhone. It wasn’t an iPhone 7, mind you, but the principle was the same. I’d bought a cheap replacement screen online, convinced I could save a few bucks. Then I hit the bottom. Tiny, weird-looking screws I’d never seen before. Panic set in. I fumbled with it for what felt like hours, convinced I’d just ruined a perfectly good phone over a bit of cracked glass and some obscure fasteners.
That initial frustration led me down a rabbit hole of understanding how these things are actually built, and more importantly, how they’re meant to be repaired. So, let’s cut to the chase. If you’re wondering how many pentalobe screws are found in the iPhone 7, the short answer is surprisingly few, but their importance is massive.
Those Tiny Pentalobe Screws: What’s the Deal?
Apple started using those peculiar Pentalobe screws on the iPhone 4, and they’ve been a staple ever since. The main reason? Security and proprietary control. They’re not something you’ll find in your standard toolbox, and that’s entirely by design. It’s their way of saying, ‘Hey, this is our product, and if you want to mess with it, you’ll need our tools.’ It’s infuriating for DIYers, but from a manufacturing standpoint, it makes sense for them. It prevents easy unauthorized access and keeps the repair market a bit more controlled, or at least requires specific tools to enter.
When you’re looking at an iPhone 7 specifically, the Pentalobe screws aren’t actually inside the main body of the phone where the logic board and battery are. Instead, they serve a very specific, and frankly, very important purpose: they secure the bottom of the phone’s exterior casing to the rest of the chassis. Think of them as the gatekeepers to the internal components. Without removing them, you can’t even start to peel away the screen assembly, which is the first major hurdle in any repair. They are the entry point, and if you’ve ever looked at the bottom edge of an iPhone 7, you’ll see them right there, flanking the charging port.
Most people looking into this are probably in one of two camps: either they’re curious about the engineering behind the device, or they’re about to embark on their own repair mission and need to know what they’re getting into. For the latter, knowing the exact number and location is most important. You don’t want to be halfway through a repair, realize you missed a screw, and have to backtrack. I’ve definitely been there, and it’s a special kind of annoyance. The Pentalobe screw size for the iPhone 7 is typically a P2, which is a 5-point star shape. It’s small, and the head is designed to strip easily if you use the wrong screwdriver, which is another delightful Apple trademark.
The common advice you’ll find online often glosses over the specifics of the iPhone 7’s Pentalobe screw count, lumping it in with other models. But for a precise repair, or even just for satisfying your curiosity, you need the exact numbers. It’s not a huge number, but it’s enough to be a significant barrier if you’re not prepared. The key takeaway here is that these screws are your absolute first step in accessing the internals, and understanding their role is fundamental to any hands-on interaction with the device.
The Actual Number and Where They Live
Alright, let’s get down to brass tacks about how many pentalobe screws are found in the iPhone 7. Drumroll please… there are two of them. That’s it. Just two little Pentalobe screws, located at the very bottom of the phone, one on either side of the Lightning port. They’re usually the first thing you see when you flip the phone over, and they’re what hold the bottom edge of the display assembly to the main frame. They look identical, and they are the same size.
This is a important piece of information for anyone attempting a repair. When you’re buying a repair kit, make sure it includes the correct Pentalobe screwdriver. Most reputable kits will bundle a P2 Pentalobe driver, a Philips head driver, and sometimes a Tri-point driver (though the iPhone 7 doesn’t use Tri-point for its main external screws, it’s good to have one for later models). The Pentalobe screws on the iPhone 7 are not particularly long, but they are under constant tension from the display assembly pressing against them, so they can sometimes be a bit stubborn to get out.
I’ve seen people try to brute-force these screws with ill-fitting screwdrivers or even regular flatheads in a pinch. Don’t do it. Seriously. The heads are soft and designed to cam out easily if you apply too much lateral force or use the wrong bit. You’ll end up with a stripped screw head, which is exponentially more difficult to remove and can lead to damaging the surrounding aluminum casing. It’s far better to spend $10 on a proper Pentalobe screwdriver than to risk damaging your phone or spending hours trying to extract a mangled screw.

The Pentalobe screws are integral to the structural integrity of the lower portion of the iPhone 7. They prevent the display assembly from separating prematurely, especially during everyday use where the phone might be handled roughly or even dropped. While two screws might seem like a small number, their strategic placement makes them highly effective at their job. So, when you’re looking at your iPhone 7, just remember those two tiny screws at the bottom are your first and most important obstacle to internal access.
Why Pentalobe? Apple’s Engineering (and Business) Choices
So, why Pentalobe? Why not just stick with the ubiquitous Phillips head screws that have been the standard for electronics for decades?
Apple’s move to Pentalobe was a deliberate one, stemming from their desire to differentiate their products and maintain a higher degree of control over repairs. It’s a classic Apple move: create a unique ecosystem, even down to the fasteners. Initially, when they introduced them with the iPhone 4, it was a surprise to many.
It wasn’t just about making repairs harder; it was also about achieving a very clean, smooth exterior design. The Pentalobe screws allowed for a flush fit without any visible screw heads on the front or sides of the device, contributing to that sleek, minimalist aesthetic they were going for.
From a repair perspective, it’s a pain. You need specialized tools. This is why a lot of third-party repair shops initially struggled or charged a premium. However, it also pushed the market for repair tools. Now, Pentalobe drivers are readily available, and frankly, they’re not that expensive. I picked up a decent set for about $18 that included a few different sizes and other common bits. It’s a small investment for the ability to tackle most phone repairs yourself. But the initial barrier was definitely a business strategy.
There’s also an argument to be made about structural rigidity. While two screws might not sound like much, they are located at the point where the display assembly is most susceptible to pressure and flex. By using these specific screws, Apple makes sure that the bottom edge of the display is firmly anchored. This is particularly important for water-resistance seals (though the iPhone 7’s water resistance was more ‘splash-resistant’ than fully waterproof, unlike later models). If the seal is compromised by a loose display assembly, water ingress becomes a much bigger problem.
Contrarian opinion time: While everyone complains about the Pentalobe screws, I actually don’t mind them as much anymore. Yes, they’re an annoyance if you don’t have the right tool. But they are also very distinct. You’re not going to accidentally grab a random Phillips screw and try to force it in. When you see those little star-shaped heads, you know exactly what you need. It removes ambiguity, which, ironically, can prevent other types of repair mistakes. It’s a trade-off: increased difficulty in obtaining the tool versus reduced confusion during the actual repair process. For the iPhone 7, it’s just those two, so it’s a minor hurdle.
What You Need to Know Before You Turn That First Screw
Before you even think about touching those Pentalobe screws on your iPhone 7, there are a few things you absolutely need to have in your arsenal. First and foremost is the correct screwdriver. As I’ve stressed, this is a P2 Pentalobe driver. Don’t try to fake it. You can find these online for less than the cost of a cup of fancy coffee. Make sure it’s from a reputable seller; cheap knock-offs can be made of soft metal and will strip easily, either the screw head or the driver itself. (See Also: How Measure Metric Computer Screws )
Secondly, you need a way to keep track of your screws. While the iPhone 7 only has two Pentalobe screws, later iPhones have a multitude of screws of different lengths and types. Mixing them up can cause serious damage. For the iPhone 7, it’s less of an issue, but good habits start early. I use a magnetic project mat with grids and compartments, or sometimes just a small tray with labeled sections. For the iPhone 7, you’ll have the two Pentalobe screws, and then a few Phillips head screws holding the internal bracket and the battery connector shield. Keep them separate!
A good set of electronics spudgers and prying tools is also key. Once those two Pentalobe screws are out, you’ll need a thin, flat tool to gently pry the display assembly away from the frame. Start at the bottom, near where the screws were. Be patient. The display is held in place with clips and adhesive. You’ll hear popping sounds as the clips release, and you might need to apply a bit of heat (using a hairdryer on a low setting, for instance) to soften the adhesive, especially if it’s an older phone. Don’t force it; you risk cracking the screen or damaging internal cables.
Finally, be aware of the battery. Once you get the display open, the battery connector is usually one of the first things you’ll see and should be disconnected immediately. This is a safety precaution. Lithium-ion batteries can be volatile if punctured or short-circuited. A lost screw or a slipped tool can cause a short circuit. Disconnect the battery as soon as you can to minimize risk. For the iPhone 7, the battery connector is under a small metal bracket, which is held down by a couple of Phillips screws.
Common Mistakes and What Actually Works
The biggest mistake people make, by far, is using the wrong tools. I’ve seen people try to use a small flathead screwdriver to turn a Pentalobe screw. It’s like trying to hammer a nail with a wrench; it’s the wrong tool for the job and you’re likely to cause damage. The Pentalobe screw heads are shallow and designed for a very specific fit. Using a flathead will almost certainly strip the head, making it a nightmare to remove. Then you’re in a situation where you might need to drill out the screw or try to cut a new slot, which is advanced stuff and risky.
Another common mistake is rushing. People see those two screws at the bottom and think, ‘Easy peasy, five minutes.’ But they don’t account for stiff adhesive, corroded screws (especially if the phone has been exposed to moisture), or simply fumbling with a new tool for the first time. Take your time. If you feel resistance, stop and assess. Is the screwdriver properly seated? Are you turning it the right way? Sometimes, gently rocking the screw back and forth can help loosen it if it’s a bit tight.
Overheating is also a concern. While a little heat can soften adhesive, too much heat can damage the battery, the display, or other internal components. Be conservative with the heat. A hairdryer on its lowest setting, held a few inches away and moved constantly, is usually sufficient. Don’t blast it with a heat gun. I learned this the hard way when I accidentally warped a plastic component on an older device trying to speed up adhesive removal.
What actually works? Patience, the right tools, and a good guide. There are countless YouTube videos and online guides showing exactly how to do this. Watch a couple before you start. They’ll show you where the clips are, where the cables run, and how much force is generally acceptable. For the iPhone 7, the process is relatively straightforward compared to later models with more complex waterproofing. Focus on getting those two Pentalobe screws out cleanly, then work your way around the edges of the display. Taking the screen off is the main event, and those two screws are your gatekeepers.
| Component | Screw Type | Quantity | Verdict |
|---|---|---|---|
| Bottom Exterior | Pentalobe (P2) | 2 | Annoying but necessary. Own the right tool. |
| Internal Brackets (Display/Shields) | Phillips (small) | ~4-6 (varies slightly) | Standard, easy to manage. Keep track of length! |
Can I Use a Regular Flathead Screwdriver for iPhone 7 Pentalobe Screws?
No, absolutely not. While it might seem tempting in a pinch, a flathead screwdriver will almost certainly strip the Pentalobe screw head. These screws have a unique 5-point star shape that requires a matching Pentalobe driver. Using the wrong tool will damage the screw and make removal much more difficult, potentially damaging the phone’s casing. (See Also: How To Adjust Eyeglass Screw )
How Do I Know If I Have the Right Pentalobe Screwdriver for My iPhone 7?
For the iPhone 7, you need a P2 size Pentalobe screwdriver. This refers to the size and number of points on the star. Most electronics repair kits specifically list the sizes of the bits included. If a kit says it’s for iPhones, it should include a P2 driver. It’s a small, slender driver with a 5-pointed star tip.
Are the Pentalobe Screws the Only Thing Holding the iPhone 7 Screen on?
No, the Pentalobe screws are only at the bottom edge of the device. They secure the bottom of the display assembly to the main frame. Once those are removed, the rest of the display is held in place by clips around the edges and adhesive. You’ll need to carefully pry around the perimeter to release these clips and break the adhesive seal.
Can I Just Ignore the Pentalobe Screws?
You absolutely cannot ignore the Pentalobe screws. They are the very first fasteners you must remove to even begin separating the display assembly from the iPhone 7’s body. Without removing them, you will not be able to access any of the internal components for repair or replacement.
What Happens If I Strip an iPhone 7 Pentalobe Screw?
If you strip an iPhone 7 Pentalobe screw, it becomes very difficult to remove. You might be able to grip the remaining head with a pair of small pliers or use a specialized screw extractor. In severe cases, you may need to carefully cut a new slot into the screw head with a Dremel tool or drill it out, which carries a significant risk of damaging the phone. It’s far better to prevent stripping by using the correct Pentalobe P2 driver.
Final Thoughts
So, there you have it. The iPhone 7, a device that kicked off a new era of Apple design, is held together at its base by a mere two Pentalobe screws. It’s not a huge number, but their significance in granting access to the phone’s internals is enormous. Remember that number: two. And remember the tool: the P2 Pentalobe screwdriver.
Don’t be that person who strips the screws because they tried to be clever with a flathead or a generic tool. The common advice to just get the right tool is, for once, completely spot on. It’s a small investment for a lot less headache and a much higher chance of a successful repair or upgrade.
If you’re about to embark on an iPhone 7 repair, take a deep breath, gather your tools, watch a guide or two, and remember how many pentalobe screws are found in the iPhone 7 – just two. Get those out cleanly, and you’re well on your way. What’s the next repair challenge you’re considering?
