4-40 x 1/4 Flat Head Torx Drive Screws 100 Degree 18-8 Stainless Steel 100 Pcs.

Torx® PLUS, is designed to allow greater torque, and to minimize wear. Currently, Torx® PLUS heads and drivers are patented, slowing adoption in the marketplace. Standard Torx drivers can be used to drive Torx PLUS screws, but Torx PLUS drivers will not fit standard Torx screws. There is also a tamper resistant version of Torx PLUS, having five lobes and solid post in the center. Drivers for the tamper-resistant version are tightly controlled by Camcar, and are sold only to OEMs (along with the fasteners), or OEM-authorized repair facilities.
