Apex 1/4'' Phillips Hex Insert Bits With Anti-Camout Ribs

1/4'' Phillips® head screwdriver bits from Apex® Fastener Tools formally Cooper Tools. The Phillips® head bit is purposely designed to cam out when the screw stalls, preventing the fastener from damaging the work or the head. Painted, coated or corroded fasteners can present special problems. Apex® ACR insert bits' special wing-face ribs grip screw recesses to reduce stripping and cam-out which can result in damage to the surrounding workpiece.

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.
