Genius Tools Impact Socket 21mm 1/2 Inch Drive Thin Wall 12-Point CR-Mo Steel - 453821 Impact Socket

This 21mm thin wall impact socket is built for tight-clearance fastening where a standard wall thickness won’t fit. The 12-point design helps engagement on compatible fasteners, while the 1/2" drive format keeps it aligned with common impact tools and professional socket systems.

Constructed from Chromium Molybdenum Alloy Steel (CR-Mo), it is designed for high strength and durability with anti-corrosive properties. A matte black oxide coating and oil-quenched heat treatment support long-term service with a tough exterior and strong inner core.
