Security Torx Bits/Tamper Proof Torx bits/Pin-in Torx bits
We have security torx available in a rack or in a Security Bit Set Simply put, security torx screwdriver bits are like regular torx bit sets except that the bits have a hole drilled into the end that fits into the screw. Tamper-proof torx screws have a pin in the center that fits into the whole in the bit. The pin in the secuirty tor x screws prevents you from using a regular Torx bit/star bit or torx wrench/star wrenches.
Many people want to know the difference between Torx bit sets and star bit sets.
Chapman star bits fit Torx screws, but are a unique, improved version of Torx bits. Torx screws are also known as 6 star screws or 6 point star screws.
Torx head bits are a licensed product that requires manufacturers to follow their part prints. We feel that our Chapman star bits are an improvement on the official Torx bits. The working end of our star bits are precision machined to fit Torx screws, but the shank of the bits have the signature Chapman length and knurled end. The working end that fits into the Torx screw is precision milled and the bits match our standard length of just over 1" with ball detent to hold it into our tools. They also feature our signature knurled end for delicate finger tightening. We improved on the ear stops with a strong ring stop that keeps the bit in place in our famous midget ratchet.
