MacBook Pro Screwdriver Sizes
Most modern MacBook Pro models use Pentalobe screws on the bottom case and smaller Torx screws inside. Older pre-Retina models are more likely to use Phillips screws on the case.
| Model Year | Bottom Screws | Internal Screws |
|---|---|---|
| 2009-2012 | Phillips #00 | Torx T4, T6 |
| 2012-2015 | Pentalobe P5 | Torx T5, Phillips #00 |
| 2016-2020 | Pentalobe P5 | Torx T5, T3 |
| 2021 onwards | Pentalobe P5 | Torx T5, T3, T8 |
MacBook Air Screwdriver Requirements
MacBook Air models commonly use a Pentalobe P5 screwdriver for the bottom case. Internal screws vary by generation, so check the exact model before removing batteries, boards or brackets.
| Model Year | Bottom Screws | Internal Screws |
|---|---|---|
| 2010-2017 | Pentalobe P5 | Phillips #00, Torx T5 |
| 2018 onwards | Pentalobe P5 | Torx T5, T3, T8 |

iPhone Screwdriver Sizes
iPhones use very small screws, and the bottom screws are usually different from the internal screws. Screen removal also carries extra risk because display cables, Face ID parts and seals can be damaged easily.
| Model | Screwdriver | Size | Use |
|---|---|---|---|
| iPhone 4 onwards | Pentalobe | P2, 0.8mm | Bottom screws |
| iPhone 3G/3GS | Phillips | PH000 | External and internal screws |
| Many iPhone models | Phillips | PH000 | Some internal screws |
What Size Screwdriver FAQ
- What size screwdriver opens a MacBook Pro?
Pentalobe P5, also known as 1.2mm, is commonly used for the bottom case on Retina and newer MacBook Pro models. Internal screws often require Torx T3, T5 or T8. - What screwdriver opens a MacBook Air?
Most MacBook Air models use Pentalobe P5 for the bottom cover. Older internal parts may use Phillips #00 or Torx T5. - What screwdriver do iPhones use?
Most iPhones use Pentalobe P2, 0.8mm, for the two bottom screws. Internal screws commonly include PH000 and other small specialist types. - Can I use a Torx screwdriver instead of a Pentalobe screwdriver?
No. Pentalobe and Torx are different shapes. A Torx bit can slip in a Pentalobe screw and round the head.
Pentalobe vs Torx Explained
Pentalobe and Torx can look similar at first glance, but they are not interchangeable. Pentalobe screws have a five-point shape and are often used on the outside of Apple devices. Torx screws have a six-point shape and are common inside MacBooks.
| Type | Shape | Typical Apple Use |
|---|---|---|
| Pentalobe | 5-point star | External MacBook and iPhone screws |
| Torx | 6-point star | Internal brackets, boards and some components |
Brief History of Apple Screw Types
Apple moved away from standard Phillips screws on many devices and adopted Pentalobe and small Torx screws across MacBook, MacBook Air, MacBook Pro and iPhone models. The result is that a normal household screwdriver is usually the wrong tool for the job.
Common Mistakes to Avoid
- Using a Torx bit in a Pentalobe screw.
- Pressing too hard and damaging the aluminium case.
- Skipping anti-static precautions before touching internal parts.
- Mixing screw lengths during reassembly.
- Opening the device before checking warranty, battery swelling or liquid damage risks.
- Forcing a screw that is already rounded or stuck.
Stripped Screw or MacBook Not Opening?
If a screw is rounded, stuck or refusing to move, do not keep forcing it. That can make the repair much harder. CWC Computers can inspect the MacBook and advise the safest next step.
MacBook vs iPhone Repairs
MacBooks usually give you more room to work than iPhones, but they still contain fragile connectors, battery hardware and tiny screws with different lengths. iPhone repairs are more compact and can involve display seals, Face ID components and delicate ribbon cables.
| Factor | MacBook | iPhone |
|---|---|---|
| Typical external screwdriver | Pentalobe P5 | Pentalobe P2 |
| Internal screws | Torx T3, T5, T8, Phillips #00 on some models | PH000 and other small internal screws |
| Main risk | Battery, trackpad, board and cable damage | Screen, cable, seal and Face ID damage |
Troubleshooting Common Issues
- Stripped screws: Stop before the screw is completely rounded. Extra force often makes extraction harder.
- Device will not boot after opening: Check whether a battery connector, display connector or internal cable has been disturbed.
- Loose parts after reassembly: Recheck screw locations and lengths. A screw in the wrong place can damage a board or casing.
- MacBook feels swollen or will not close properly: Do not force the case. A swollen battery needs careful handling.
When to Call a Professional
- You are unsure which exact MacBook model you have.
- A screw is stuck, rounded or spinning without coming out.
- The MacBook may have battery swelling or liquid damage.
- You need help with an M-series MacBook, Touch ID, charging issue or board-level fault.
- The device contains important data and you do not want to risk accidental damage.

Right to Repair and Apple DIY Repairs
Apple devices can be repaired, but the practical difficulty varies by model and fault. Some repairs need exact tools, careful battery handling, software checks or component calibration. If you only need to identify a screwdriver size, this guide should help. If you are opening a MacBook because of a fault, it is worth weighing the risk before starting.
Extended FAQ
- Can I reuse MacBook screws? Usually yes, as long as they are not worn, damaged or cross-threaded.
- Are Apple screws special? Many are specialist Pentalobe or small Torx screws, and some models use several lengths that must go back in the correct positions.
- Can I use a normal screwdriver? No. A normal household screwdriver is usually too large and can strip the screw head.
- What if my MacBook screw is already stripped? Stop turning it. Continued pressure can remove what is left of the screw head.
- Should I test before reassembly? If the repair requires disconnecting parts, testing before final reassembly can help catch loose cables or connection issues early.
Tips for Successful Repairs
- Confirm the exact model before opening the MacBook.
- Use the correct screwdriver size and keep the driver straight.
- Keep screws grouped by location and length.
- Work slowly on a clean, static-safe surface.
- Do not continue if you feel unusual resistance.
- Stop if you notice battery swelling, liquid residue or heat damage.
