The Apex magnetic impact sockets hold the fastener in the driving position, even when working straight down. Time-wasting motions are eliminated when starting fasteners or working in hard-to-reach areas. As the nut is run down, a spring-loaded or hollow cylinder magnet allows the bolt or stud to retract into the socket body. Nuts are held firmly in the socket. These Apex® impact sockets are identified with an MB- prefix.

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® impact sockets provide an exact, sure fit every time. Impact sockets from Apex® Fastener Tools 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. Impact sockets from Apex® Fastener Tools are designed and manufactured for high-impact use. Apex® impact sockets are made from stronger alloy steel than the average impact socket.
