Torx Bit

What is a Torx Screwdriver?

Called Torx, 6 point, and star, Torx are a 6 pointed star shaped screwdriver. Originally designed in the 60’s to outperform hex screws, Torx is a trademarked name for a screwdriver that fits Torx screws, commonly seen in sizes Torx 6 to Torx 40 (or T6 to T40).

Torx drivers come in a variety of shapes including: regular straight Torx drivers, Torx keys or Torx L keys, and Torx screwdriver bits. 

There are speciality variations of the Torx 6 pointed star shape such as Torx Plus, Security Torx, TX Ttap but they are uncommon and typically only used in security applications. 

Torx brand is a licensed product meaning that manufacturers need to manufacture to Torx licensed prints and specifications. To make an analogy, only Kleenex can make a product called Kleenex, but many manufacturers make facial tissues. 

Chapman Star bits are precision manufactured to fit Torx screws, but we cannot call them Torx bits because we’ve added improvements that don’t qualify under official Torx licensing. 

Unlike Torx screwdriver bits, Chapman Star screwdriver bits have a ball detent that lock into our tools without the use of magnets. This is essential for working on sensitive electronics where magnets can short out a PC board. They also feature our signature knurled end that provides good grip to finger tighten small and delicate fasteners. We manufacture the most common sizes S6, S8, S10, S15, S20, S25, S27, S30, S40 that fit screws T6, T8, T10, T15, T20, T25, T27, T30, T40. In summary, our Star bits are precision milled to fit Torx screws, but are an improvement over typical Torx screwdriver bits.  

What is a Security Torx Screwdriver?

Security Torx, or tamper proof Torx screwdriver bits have the exact same exterior shape as regular Torx or Star screwdriver bits, but have a small hole drilled in the end to accept the small pin located in the center of security Torx screws. Security Torx drivers and screws were invented to use in applications where the manufacturer doesn’t want the typical person to have the tools to adjust or remove the screw. Unfortunately, they’re often used to try to prevent people from fixing their own appliances and equipment! That’s why Chapman manufactures the most commonly used security Torx driver bits in the following sizes: T8, T10, T15, T20, T25, T27, T30.
