Silverline 1/2″ Drive 21mm Impact Socket, 6-Point, Metric

The Silverline 1/2″ Drive 21mm Impact Socket is precision-engineered for demanding applications, featuring cold-forged, hardened, and tempered chrome vanadium steel construction for exceptional durability. Its 6-point hex design provides superior grip and reduces rounding of fasteners, making it ideal for use with powered impact tools.

This industrial-grade socket features a thick-walled design for increased strength when handling repetitive high-torque tasks. The clear laser-etched size markings ensure quick identification, while the industrial phosphate coating offers excellent corrosion resistance, extending the tool’s lifespan in harsh environments. Additionally, a sidewall hole accommodates both ball and pin locking mechanisms for secure attachment to impact tools.
