The pentalobe screw is a type of security screw used by Apple Inc. since 2009. With a five-point tamper-resistant design, it helps prevent unauthorized access to the internal components of Apple devices. The unique flower-shaped pattern requires special tools, like a pentalobe screwdriver, often found in repair kits from vendors such as iFixit.
In the repair community, the pentalobe screw has been a point of discussion due to its proprietary nature. It serves as a security feature that distinguishes Apple’s products but also presents challenges for repair and replacement. Users seeking to service their own devices must have the correct pentalobe tools to remove these screws safely without damaging their devices.
All About Pentalobe Screws and Tools
Pentalobe screws are five-pointed screws developed by Apple. They are often used in Apple products to enhance security and discourage people from opening their own devices. If you’re planning to work on any modern Apple equipment, you will need a pentalobe screwdriver.
What Exactly Is a Pentalobe Screw?
A pentalobe screw has five rounded lobes, which look like flower petals. It’s a tamper-resistant fastener that makes it difficult to open a device without specialized tools.
Pentalobe Screw Sizes
Pentalobe screws come in various sizes, and it’s essential to use the correct size screwdriver for your specific device. Here’s a table outlining the common pentalobe screw sizes and their typical applications:
| Screw Size | Typical Applications |
|---|---|
| TS1 (P2) | MacBook Air (2010 onwards), MacBook Pro with Retina Display (2012 onwards) |
| TS4 (P5) | iPhone 4, 4S, 5, 5C, 5S, 6, 6 Plus, 6S, 6S Plus SE and later |
| TS5 (P6) | MacBook Pro (2009) battery |
Important: Screw sizes can vary depending on the specific device model. Before you start working on your device, make sure to check the exact screw sizes needed.

Design and Usage
This section outlines the specific design features of the pentalobe screw and its key uses in consumer electronics.
Pentalobe Identification
The pentalobe screw is a small fastener with a unique five-pointed, star-shaped pattern. Its distinct shape differs from other screw types like Phillips and Torx. To match this pattern, specialized pentalobe screwdrivers are necessary. They come in various sizes, specifically designed to fit the corresponding pentalobe screw heads which prevents damage during the process of screwing and unscrewing. Sizes vary from PL1 to PL6, with the PL1 being the smallest, often referred to as P2 in Apple’s product nomenclature.
Application in Apple Products
Apple has adopted the pentalobe screw as a commonly used fastener in their products since 2009. This screw type is found in many Apple devices, such as iPhones starting with the iPhone 4, MacBooks including the MacBook Pro with Retina Display, MacBook Air, and even the Apple Watch. Its application has been both practical and strategic as it deters disassembly by people not having the appropriate pentalobe screwdriver, which contributes to Apple’s control over repairs and maintenance of its products. Apple brands its smaller pentalobe screws as P2, while the size slightly larger is known as P5, corresponding to the PL4 size in standard nomenclature.
Repair and Replacement
When it comes to repairing Apple devices, one often encounters the pentalobe screw. They secure parts like the battery and cases, yet require specific tools for removal. Understanding the right techniques and knowing where to seek professional help can save time and ensure a smooth repair process.
Tools and Techniques
To remove or replace pentalobe screws, one needs a precision pentalobe screwdriver–often referred to as an Apple specialty tool 922-9101 or a P2 driver. It’s unique, resembling a small flower with five points. Repair guides, like those from iFixit, detail the step by step process to handle these screws safely. For example, to open an iPhone, a P2 pentalobe driver is essential. Other types, like Torx or Phillips, won’t work due to the screw’s special design.
A good grip and proper alignment are crucial to avoid stripping the screw head. For those stripped or stubborn screws, the super glue method can serve as a temporary fix. They apply a tiny bit of glue to the screwdriver tip and then press it to the screw to turn it out once dry. Handles made from materials like Wiha enhance comfort and the user’s grip, aiding the delicate work of dealing with extremely small screws.
Aftermarket Services
Not everyone feels comfortable tinkering with their devices. In such cases, third-party repair services come into play. These independent service providers offer services ranging from battery replacements to fixing parts held by pentalobe screws.
They often provide aftermarket parts, which can be as reliable as original ones. Repair shops must navigate Apple’s closed ecosystem with a culture that leans more towards exclusive repair channels. But a growing trend in the culture of reuse and the ‘seven Rs’—a Treehugger concept advocating for responsible consumption—encourages repairs to extend device lifespan. Engaging these services can help, especially when specialized tasks are beyond one’s skill level.
Frequently Asked Questions
This section addresses common inquiries regarding pentalobe screws, including their uses, sizes, and how to handle them. It provides practical advice and information tailored to assist anyone working with these unique fasteners.
What are the typical applications of pentalobe screws?
Pentalobe screws are mainly used in electronic devices to discourage disassembly. They are often found securing components in smartphones, laptops, and other compact, high-value electronics.
What are the different sizes of pentalobe screws available?
Six sizes of pentalobe screws exist, ranging from 1 to 6, with each size denoted by a ‘PL’ followed by the size number, like PL1. These sizes cater to various electronic devices, with smaller screws typically found in compact gadgets.
How does one remove a pentalobe screw without the specific screwdriver?
Removing a pentalobe screw without the correct screwdriver is challenging and not recommended as it can damage the screw. In a pinch, one could use a small flathead screwdriver that fits tightly across the pentalobe’s points but obtaining the correct pentalobe screwdriver is the best practice.
Is there a difference between pentalobe and Torx screws?
Yes, pentalobe screws have five rounded points and resemble a flower, while Torx screws have six points with straight sides. These design differences mean Torx and pentalobe tools are not interchangeable.
What are the identifying features of a pentalobe screwdriver?
A pentalobe screwdriver has a star-shaped tip with five rounded points. The tip matches the unique five-point star shape of pentalobe screws, which distinguishes it from other screwdrivers like Phillips or Torx.
What devices commonly utilize pentalobe screws for security?
