1/2" Sq. Dr. Impact Wheel nut Socket 19x21mm

Ko-ken impact wheel nut sockets exemplify precision engineering designed specifically for high-performance wheel service operations. This dual-size 1/2 inch square drive socket features 19mm and 21mm hex openings on opposite ends, providing versatile coverage for the most common wheel fastener sizes in automotive and light truck applications. Manufactured from premium chrome molybdenum steel through Ko-ken's proprietary impact-grade heat treatment process, this socket withstands the extreme forces generated by pneumatic and cordless impact wrenches while maintaining dimensional accuracy through thousands of wheel changes. The precision-machined hex profiles distribute driving forces evenly across fastener flats, virtually eliminating rounded lug nuts while delivering maximum torque transfer for efficient wheel removal and installation.
