Hex Impact Socket Cr-Mo 1/2" 21 mm Hanger, Proline

Hex impact socket in 21 mm with a 1/2" square drive from Proline, made from chromium-molybdenum (Cr-Mo) steel and supplied on a hanger. The socket is used with pneumatic tools and is built for demanding working conditions and varying loads.

The Cr-Mo steel gives a longer working life, twice the tensile strength and three times the yield point of ordinary sockets made from chromium-vanadium steel. The corners between the work surfaces have a specially rounded profile in the PRO-DRIVE system, which spreads the point loads in the internal edges of the socket. This gives higher torque without the socket wall cracking and protects the edges of the bolt head.

The square drive fits most locking mechanisms on pneumatic tools. Weight: 0.091 kg.
