Torxalign bits "wedge" into the Torx recess to firmly hold the fastener to the bit and in most cases, a magnetic bit holder is not required. They are also good for use with stainless steel fasteners that are non-magnetic.

Tamper resistant Torx screws feature a post in the center of the recess -- this post will only fit into a tamper resistant Torx bit. Tamper resistant Torx bits are available on a restricted distribution basis.  Contact us by e-mail or phone if you have any questions about tamper proof (sometimes called "Security" screw) details.

Torx Plus bits and fasteners feature a greater engagement area for higher torque transfer and reduced camout when driving Torx Plus fasteners. They can provide up to 100% more drive cycles. Torx Plus bits are not compatible with standard Torx fasteners.
