Thin wall impact sockets from Apex Fastener Tools accommodate countersunk or limited clearance nut or bolt locations. Many of these impact sockets have a shouldered body design that can fit in tight quarters. Large openings on the six corners of the opening create a floating action that allows the socket to slip quickly and easily onto the nut or bolt. Ideal for compensating for imperfect alignment between the tool and fastener. Not generally recommended for impact use. These sockets are identified with a SF- prefix.

SF-19MM55 Apex 19mm Surface Drive Thin Wall Metric Extra Long Socket, 1/2” Square Drive from Apex Fastener Tools formally Cooper Tools, have hex tolerances that are on average 48% tighter than DIN and 35% tighter than ANSI requirements. SF-19MM55 Apex 19mm Surface Drive Thin Wall Metric Extra Long Socket, 1/2” Square Drive provide an exact, sure fit every time. Apex 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 impact sockets are designed and manufactured for high impact use. SF-19MM55 Apex 19mm Surface Drive Thin Wall Metric Extra Long Socket, 1/2” Square Drive are made from stronger alloy steel than the average impact socket.
