Wera 8790 HMC Deep 1/2" Drive Hexagon Socket Metric

The Wera 8790 HMC Deep 1/2" Drive Hexagon Socket in 21mm is a practical choice for larger metric fixings encountered in automotive, construction, and heavy engineering environments. At this size, the deep socket design is particularly beneficial, providing the reach needed for fasteners set into deep pockets or fitted with protruding threaded rods. Built to ISO 2725 part 3, the socket is crafted from matt chromed chrome-vanadium steel for robust, long-lasting performance. The hexagonal profile delivers maximum contact across all six bolt flats for accurate, high-torque tightening and loosening, with far less risk of rounding than double hexagon designs. The ball intercept ring ensures the socket stays firmly seated on the 1/2" drive in all operating conditions. Knurling at the base provides a sure grip during manual use, and the Take it easy colour-coding keeps identification simple.
