Wera Range of 8790 C Impaktor Sockets with 1/2-inch Drive, Individual Sockets

Wera Brand: Wera

The Wera 8790 C Impaktor Socket with 1/2" Drive impact sockets are designed for use with 1/2" drive (12.5mm) electric or pneumatic impact wrenches.

The Impaktor technology ensures above-average service life, even under extreme conditions. With Take it easy tool finder with colour coding by size - for quick and easy location of the required tool. Featuring a hexagonal profile and grooved socket. The hexagon profile allows the transmission of high forces and puts less strain on the edges of bolts or screw heads than a double hexagon profile.
Made from chrome-molybdenum steel with a matt black finish, the sockets have a cross-bore retaining pin hole and groove and ring socket, allowing the socket to be secured with either a locking pin or O-ring on the power tool.

The Impact 1/2" sockets are available in a range of sizes from 13 x 38mm to 21 x 38mm.
