Torx Screw
What is a Torx Screw?
Torx is a star-patterned screw drive on the head of screws. It is commonly known by different names like six-lobe or star drive while it’s called hexalobular as its ISO name.
Torx screws can have internal and external drives yet it’s usually found within the socket of the head for driving the screw during installation or removal. Torx drive can withstand high torque force that will less likely damage or cause fatigue to the screw when driven on the surface of materials.

Torx Screw Design
Star Shape
A Torx screw has a special six-point star shape. This shape is not just for looks. It lets you use more force without slipping or breaking the screw. Here are some reasons why this star shape is helpful:
- The six points spread the force across the screw and tool.
- You can use more torque and not strip the screw head.
- The rounded parts help stop damage to the screw and tool.
- The shape gives a strong grip, so the screwdriver does not slip.
- You get better control and can line things up easily, even in small spaces.
- The star shape is great for jobs that need high precision, like in cars, electronics, and airplanes.
- Your tools and screws will not wear out as fast, so they last longer.
Tip: The star shape also helps machines on assembly lines. Machines can put in Torx screws fast and right, which saves time and lowers mistakes.
Head Styles
Torx screws have many head styles. Each style works best for a certain job or industry. Here is a table to show the most common types and where you might use them:
Torx Head Style | Description & Features | Typical Applications |
---|---|---|
Standard Torx | Six-point star, good torque transfer, stops cam-out | Cars, bikes, computers, electronics, DIY projects |
Torx Plus | Squarer lobes, stronger, lasts longer | High-torque and heavy-duty uses |
Torx TTap | Tapered tip, thin walls, cuts threads in plastics and composites | Enclosures, housings |
Security Torx | Pin in the middle for extra safety | Car ignition systems, high-security areas |
External (Inverted) Torx | Head looks like a Torx bit, used with a socket | Motors, gearboxes, tight spaces |
AudiTorx | Break-away drive for tamper-proof fastening | Railroad industry |
You can pick the head style that fits your project. For example, use Security Torx if you need more safety. If you work in a small space, try External Torx.
Cam-Out Resistance
Torque Transfer
You want a screw that stays put when you turn it. The Torx screw gives you that advantage. Its star-shaped pattern lets you apply more force without the tool slipping out. This means you can tighten or loosen screws with less risk of stripping the head. The design spreads the force across six points, so you get a strong grip every time.
- Torx screws maintain a better grip on the driver, even when you use high torque.
- The star shape reduces the risk of slippage and cam-out, especially in tough jobs like construction or auto repair.
- Many users say Phillips screws strip easily, but Torx screws rarely do.
- Experts recommend Torx as the standard drive because it performs better than Phillips.
The Ultimate Guide to Fastener Drives explains that the six-point star shape allows for higher torque and superior resistance to cam-out. You get more control and less damage to your screws and tools.
Tool Fit
Picking the right tool for your Torx screw matters. If you use a bit that fits perfectly, you lower the chance of stripping the screw head. The best fit happens when the driver reaches the base of the screw socket. This lets the force spread along the whole wall of the screw recess.
- Using a bit that is too big or too small causes poor seating and increases the risk of stripping.
- A proper fit means the driver bottoms out fully, giving you even torque and less chance of cam-out.
- Ill-fitting bits can damage both the screw and the tool, leading to extra costs and frustration.
- Matching the screwdriver bit size exactly to the Torx screw size makes your work faster and more effective.
Tip: Always check the size before you start. A snug fit keeps your screws and tools in good shape and helps you finish your project with less hassle.
