Look, I’m not going to lie. The first time I ever tried to crack open an iPhone – I think it was an iPhone 5, a hand-me-down I was trying to fix for my nephew – I stared at those little star-shaped screws on the bottom and thought, “What fresh hell is this?” I’d dealt with Phillips, flatheads, even those tiny Torx screws that feel like they were designed by elves. But pentalobe?
That was new. And the question on my mind, like yours probably is right now, was specifically: how many pentalobe screws in iPhone 7?
It’s not just a random number; it’s the first barrier to entry for anyone wanting to do their own repairs or just understand what’s holding their beloved device together.
It’s easy to get lost in the weeds with repair guides and tiny parts. You’ve got battery replacements, screen swaps, charging port fixes – and every single one seems to involve a unique set of fasteners that make you question your sanity and your toolbox.
The Bottom Line: Two Pentalobe Screws on the iPhone 7
Let’s cut to the chase. If you’re asking specifically about the iPhone 7 and how many pentalobe screws are holding its lifeblood in, the answer is blessedly simple: two. That’s it. Two little pentalobe screws, located on the bottom edge of the phone, flanking the charging port. These are the very first fasteners you’ll encounter when you begin any teardown, be it for a DIY battery swap, a screen replacement, or just a deep clean. They’re the gatekeepers, and frankly, Apple uses them specifically to make it a little harder for you to go poking around inside without the right tools.
Now, why pentalobe? Apple’s been using them for years, and the common wisdom is that it’s a proprietary fastener designed to deter unauthorized repairs and encourage people to go through official channels (which, let’s be honest, usually cost an arm and a leg). The pentalobe P2 size is the one you’ll be dealing with for the iPhone 7’s external screws.
They have five points, hence the name ‘pentalobe’ (or ‘pentacle’ if you want to get fancy). The driver for these isn’t something you’ll find in your grandpa’s toolbox. You’ll need a specific pentalobe screwdriver, usually a P2 size, to get them out.
They aren’t long, and they don’t require a ton of torque, but if you try to force a regular Phillips head in there, you’re just going to strip the screw head, which is a whole other level of annoyance.
My first experience with pentalobe screws, beyond just seeing them on a parts list, was trying to replace a cracked screen on an older iPhone. I’d bought a generic repair kit online that claimed to have all the tools. It came with a tiny screwdriver that looked vaguely star-shaped. When I tried to get the first screw out, it just spun. No grip. Nothing. I ended up having to order a proper pentalobe driver separately, which of course, delayed the whole repair by three days. So, lesson learned: don’t skimp on the right tool. For the iPhone 7, it’s two screws, and you need a P2 pentalobe driver.
The Pentalobe Screw: What It Is and Why It’s There
So, we know there are two pentalobe screws on the iPhone 7, sitting there innocently at the bottom. But what exactly is a pentalobe screw? The name itself gives you a clue: ‘penta’ meaning five, and ‘lobe’ referring to the lobes or points of the screw head. These aren’t your standard Phillips or Torx screws. Instead of four or six points, they have five, arranged in a star-like pattern. Apple’s preferred flavor is the P2 size, which is a 1.2mm point size. This is distinct from other pentalobe sizes used on different Apple devices or even other manufacturers if they decide to get creative.
The primary reason Apple uses these proprietary screws is pretty straightforward: control. By using a fastener that isn’t readily available in every hardware store or standard toolkit, they make it more difficult for the average person (or even a less-equipped technician) to open up their devices. This is often framed as a security measure or a way to make sure quality repairs are done by certified professionals.
The reality, as anyone who’s tried to fix their own gear knows, is that it’s a way to steer people toward their authorized repair network, which usually comes with a heftier price tag. It’s a business decision, plain and simple, dressed up as consumer protection.
It also means that if you plan on doing any DIY repairs on your iPhone 7, you absolutely must have the correct pentalobe screwdriver. (See Also: How To Fix Eyeglasses Arm Without Screw )
I’ve seen people try to use tiny flathead screwdrivers or even bend paperclips to get these screws out. It’s a fool’s errand. You’re far more likely to damage the screw head, making it impossible to remove even with the correct tool, or worse, damage the internal components of the phone. The pentalobe driver has precisely shaped tips that slot into the five lobes of the screw head, providing the necessary grip to loosen and remove it without causing damage.
For the iPhone 7, these two screws are on the bottom edge, right next to the Lightning port. They’re usually the same length, but it’s always good practice to keep track of where each screw came from, as even minor differences can matter in reassembly.
Beyond the Two: Other Screws You’ll Find
While the iPhone 7’s external pentalobe screws are the ones most people are curious about when asking how many pentalobe screws are in iPhone 7, it’s important to know that’s not the only type of screw inside. Once you’ve successfully navigated those initial two pentalobe fasteners, you’ll find a whole host of other screws used throughout the device. Apple is notorious for using a dizzying array of screw types and sizes internally. This is where things can get really frustrating for DIY repairers.
After the pentalobe screws are out and the display assembly is lifted, you’ll encounter Phillips head screws, typically smaller ones, holding down bracket covers for the display connectors, battery connector, and other components. These Phillips screws come in various sizes, often labeled as #000 or #00. There are also Y-type (Tri-point) screws used in later iPhone models, but the iPhone 7 primarily sticks to Phillips and the initial pentalobe ones for its main structural components.
However, be warned: even within the Phillips screws, there can be subtle length differences. Mixing them up can lead to stripped threads, damage to the logic board, or even puncture the battery if you use a screw that’s too long in the wrong place. I learned this the hard way when I tried a quick battery swap on a friend’s iPhone 8.
I used a screw that looked identical, but it was a millimeter too long for one spot, and I felt a little pop. Thankfully, it didn’t pierce anything, but it was a nail-biting moment.
The internal screw situation is a testament to Apple’s design philosophy: compact and secure. Every millimeter counts, and that extends to the fasteners used. For the iPhone 7, once those first two pentalobe screws are out, prepare yourself for a mix of Phillips screws. It’s advisable to have a good quality, magnetized screwdriver set that includes a variety of small Phillips bits and, of course, the P2 pentalobe driver. Some repair kits even come with a magnetic mat that has labeled spots for each screw, which is an absolute lifesaver for keeping track of everything. Without a good system, you’re looking at a reassembly nightmare.
The Right Tools for the Job: More Than Just a Pentalobe Driver
Let’s be blunt: if you’re asking how many pentalobe screws in iPhone 7, you’re likely considering opening it up. And if you’re opening it up, you need the right tools. While the pentalobe driver is the star of the show for those initial two screws, it’s by no means the only tool you’ll need. The entire internal construction of the iPhone 7 is a delicate dance of small parts and even smaller screws, and a half-hearted approach with the wrong tools is a recipe for disaster. I’ve seen too many friends trash perfectly fixable phones because they tried to make do with inadequate equipment.
First and foremost, the P2 pentalobe screwdriver is a must. You can find these online for a few dollars. Don’t buy the cheapest one you see; look for one with decent reviews and a comfortable grip. A magnetized tip is a huge plus, as it helps hold the tiny screws so they don’t fall into the abyss of the phone’s internals. Beyond that, you’ll absolutely need a set of small Phillips head screwdrivers, specifically sizes #000 and #00. These are for the internal screws that hold down connector brackets and other components. Again, a magnetized tip is your best friend here.
What else? A spudger is key.
This is a plastic or nylon tool, often with a flat end and a pointed or hook-like end. It’s used for prying open delicate connectors, separating adhesive, and gently lifting components. Metal tools can easily scratch or damage the logic board or other sensitive parts, so plastic is the way to go.
Tweezers are also incredibly useful for picking up tiny screws, manipulating flex cables, and placing small components. A suction cup is often needed to help lift the display assembly away from the chassis, especially if the adhesive is still somewhat intact. (See Also: How Measure Metric Computer Screws )
Finally, a heat gun or a hairdryer can be helpful for softening the adhesive around the screen, making it easier to pry open. But be careful with heat; too much can damage the battery or other components.
Here’s a quick rundown of what you should have:
| Tool | Purpose | Verdict |
|---|---|---|
| P2 Pentalobe Screwdriver | Removes the two external bottom screws. | Key – No substitutes. |
| Phillips Head Screwdrivers (#000, #00) | Removes internal screws. | Key – Have multiple sizes. |
| Spudger | Prying connectors, separating adhesive. | Highly Recommended – Protects components. |
| Tweezers | Handling small parts, screws, cables. | Very Useful – Precision work. |
| Suction Cup | Lifting the display assembly. | Recommended – Makes opening easier. |
Investing in a good, complete toolkit isn’t just about having the right tools; it’s about saving yourself a massive headache and potential damage. It’s a few bucks well spent.
Common Mistakes and How to Avoid Them
So you know there are two pentalobe screws in iPhone 7, you’ve got the tools. Great. But there’s more to a successful repair than just having the right bits. Over the years, I’ve seen (and made) a fair share of mistakes when tinkering with phones. The biggest one, hands down, is impatience. You’re in a hurry to fix it, or maybe you’re just eager to see it working again, and you rush through the steps. This is where things go wrong.
The most common mistake, after not having the right pentalobe driver, is mixing up the internal screws. As I mentioned, even within the Phillips screws, there are length variations.
Putting a screw that’s too long into a hole meant for a shorter one can lead to catastrophic damage. You could puncture the logic board, damage a tiny component, or even go right through the battery casing, which is incredibly dangerous. Always, always, always lay out your screws in an organized manner. A magnetic mat with labeled sections is gold.
If you don’t have one, use a piece of paper and draw a diagram of where each screw came from. Don’t eyeball it; measure if you have to.
It sounds tedious, but it’s infinitely better than frying your phone.
Another mistake is being too rough with connectors. The cables that connect the display, battery, and other components to the logic board are delicate. They have tiny pins and are secured by small clips or screws. Trying to rip a connector off without properly releasing it can tear the pins or the cable itself. Always use a spudger to gently lift connectors straight up. Never yank. Similarly, when you’re lifting the display assembly, remember it’s still connected by a few cables. Don’t just rip it off. Pry gently and see where it’s still attached.
Lastly, static electricity is a silent killer of electronics. Before you touch any internal components, ground yourself. Touch a metal object connected to the earth (like a metal desk leg or the unpainted metal casing of a plugged-in computer). Some repair kits come with an anti-static wrist strap, which is a worthwhile investment if you plan on doing a lot of electronic repair. For the iPhone 7, these two pentalobe screws are just the beginning of a careful process.
Practical Tips for Your iPhone 7 Repair Journey
Alright, you’ve got the knowledge: two pentalobe screws on the iPhone 7 are your entry point. You’ve got the tools. Now, let’s talk about making the actual process as smooth as possible. Honestly, most of the difficulty with these repairs isn’t the complexity of the hardware itself, but the user’s own approach and preparation. So, here are a few tips I’ve picked up that have saved me time, money, and a lot of stress.
First, watch a video guide before you start. Not just any video, but one that’s specifically for the iPhone 7 and ideally by a reputable repair source. iFixit is usually my go-to. Watch the entire thing through once. Then, watch it again, pausing at key moments, and get your workspace ready. Lay out your tools, your magnetic mat, and have your replacement parts within reach. A well-lit workspace is also important. Trying to do this in dim light is a recipe for frustration and mistakes. (See Also: How To Adjust Eyeglass Screw )
Second, be patient with the adhesive. The iPhone 7, like many modern smartphones, uses adhesive to seal the display to the frame.
This makes it water-resistant (or at least water-resistant-ish, don’t go swimming with it). When you’re trying to pry the screen off, you’ll need to warm up the edges slightly. A hairdryer on a low setting or a heat gun on its lowest setting, applied evenly around the perimeter for about a minute, will soften the adhesive. Then, use your suction cup and a thin plastic opening tool (like a guitar pick or a thin spudger) to carefully work your way around the edges.
Go slow. Don’t force it.
If you meet resistance, apply a little more heat or try a different spot.
Third, when you’re putting it back together, don’t overtighten the screws. Once a screw feels snug, stop. Overtightening can strip the threads in the aluminum frame, which means that screw will never hold securely again. This is particularly true for the tiny internal Phillips screws. They don’t need much torque at all. Finally, remember to reconnect all the cables properly. Make sure they click into place. A loose cable is the most common reason a phone won’t boot up after a repair. Double-check everything before you close it up. The pentalobe screws go back in last, and they should only need a gentle tighten to secure the display.
Faq: Your Burning iPhone 7 Screw Questions Answered
Do I Need a Special Screwdriver for the iPhone 7?
Yes, you absolutely do. For the two screws on the bottom edge, you’ll need a P2 pentalobe screwdriver. These are not standard screwdrivers you’ll find in most household toolkits. Trying to use a regular Phillips or flathead screwdriver will likely strip the screw head, making removal impossible even with the correct tool. It’s worth buying a dedicated pentalobe driver; they are inexpensive and readily available online.
Are All the Screws Inside the iPhone 7 Pentalobe?
No, only the two screws on the bottom edge of the iPhone 7 are pentalobe. Once you remove those and open the phone, you will encounter various sizes of Phillips head screws used to secure internal components and bracket covers. It’s important to keep track of these different screw types and lengths during disassembly to avoid damage during reassembly.
What Happens If I Strip an iPhone 7 Pentalobe Screw?
Stripping a pentalobe screw head is a frustrating problem. It means the tool can no longer get a grip to turn the screw. In mild cases, you might be able to use a slightly larger rubber band between the screwdriver and the screw head to get some extra grip, or even try a specialized screw extractor tool for electronics. However, severe stripping can make removal very difficult, sometimes requiring drilling out the screw, which is a delicate process that risks damaging the phone’s chassis and internal components.
Can I Use a P1 or P5 Pentalobe Driver on an iPhone 7?
No, you should not. The iPhone 7 specifically uses the P2 size pentalobe screw. While other pentalobe sizes exist for different Apple devices (like the P1 for older iPhones or the P5 for MacBooks), using the wrong size driver will not fit properly. It won’t engage the screw head correctly and will likely lead to stripping the screw, rendering it impossible to remove with the proper tool. Always use the P2 size for the iPhone 7.
Final Verdict
So, to recap the main event: if you’re wondering how many pentalobe screws in iPhone 7, the answer is a straightforward two. They’re the gatekeepers, the first hurdle in getting inside your device. But as we’ve seen, while knowing the number is easy, the real challenge lies in having the right tools and the patience to go with them.
Don’t be that person who strips the screw head and ends up in a panic. Invest a few dollars in the correct P2 pentalobe driver and a decent set of small Phillips bits. Watch a video guide, keep your screws organized, and work methodically. It’s not rocket science, but it does require a bit of care and attention to detail.
If you’re feeling overwhelmed, there’s no shame in taking it to a professional. But if you’re up for the challenge and want to save a few bucks, armed with the right knowledge and tools, you can absolutely tackle a basic repair on your iPhone 7. Just remember: two pentalobe screws, and a whole lot of other tiny parts that need respect.
