Socket 6 points 3/4" 43mm - 18993. Designed for use with pneumatic tools, it is suitable for working in heavy conditions and under varying loads. Made from durable chromium-molybdenum steel (CrMo), offering increased lifespan with twice the resistance to fracture and triple the resistance to deformation compared to sockets made from chromium-vanadium steel. The PROLINE socket features specially rounded corner profiles at the open angles between the working surfaces of the PRO-DRIVE system to reduce the accumulation of excessive point loads at the corners between the teeth of the socket and the bolt. This enhances the socket's durability and protects the edges of the bolt being released. Square drive sockets are compatible with most locking mechanisms found in reliable pneumatic tools. Length: 90mm Size: 43mm
