Not sure which socket you need?
Pick drive, execution and size: we generate the code of the impact socket suited to your wrench.
Rugged where it matters
Hot-forged alloy steel, machined to ISO tolerances and heat-treated for maximum impact resistance, with retaining-pin hole and o-ring.
Also available in a thin-wall version for nuts with restricted access and as power sockets for turbines and very high-torque tightening. The range is completed by extensions, adaptors, universal joints and socket sets in carrying cases.
