Impact Hex Socket Cr-Mo 3/4" 21 mm on Hanger, Proline

Hex impact socket with a 3/4" square drive and a size of 21 mm, from Proline. The socket is made of chromium-molybdenum steel (Cr-Mo) and is supplied on a hanger.

It is used with pneumatic tools and is intended for heavy working conditions and varying loads. The steel gives a longer working life than ordinary sockets in chromium-vanadium steel, with twice the tensile strength and three times the yield point.

The socket has specially profiled roundings in the obtuse angles between the working surfaces, PRO-DRIVE. This reduces point loads in the inner edges of the socket, gives higher torque without the socket wall cracking and protects the edges of the bolt head. The square drive fits most locking mechanisms in pneumatic tools.
