Apex standard length impact sockets from Apex Fastener Tools formally Cooper Tools, have hex tolerances that are on average 48% tighter than DIN and 35% tighter than ANSI requirements. Apex standard length impact sockets provide an exact, sure fit every time. Apex standard length impact sockets provide the tightest tolerances for straightness and concentricity available.

High strength fasteners in the aviation industry or high performance automotive field often require the use of an impact wrench or impact driver to deliver the amount of torque required to tighten or loosen them. Apex standard length impact sockets are designed and manufactured for high impact use. Apex standard length impact sockets are made from stronger alloy steel than the average impact socket.
