Apex Torx Female Square Service Drive Bits

Female square drive Torx service drive bits from Apex® Fastener Tools formally Cooper Tools. Torx fasteners are becoming more and more common in Automotive and appliance assembly. Apex® provides a full selection of bits for Torx screws. By design, Torx head screws resist cam-out better than Phillips head or Slotted head screws. Where Phillips heads were designed to cause the driver to cam-out, to prevent over tightening, Torx heads were designed to prevent cam-out. The reason for this was the development of better torque-limiting automatic screwdrivers for use in factories.

Rather than rely on the tool slipping out of the screw head when a torque level is reached, thereby risking damage to the driver tip, screw head and/or work-piece, the newer driver design achieves a desired torque consistently. Apex® quality begins with select raw materials, only carefully chosen, high grade tool steel is used. Each Apex® bit is manufactured to the tightest tolerances in the industry, most are even tighter than licensing agreement requirements and all Apex® bits meet the most stringent government and military specifications.
