The Wera 8790 HMC Deep 1/2" Drive Hexagon Socket in 20mm is designed for larger metric fasteners that require a steady, high-torque approach — commonly found in heavy plant, automotive, and structural steel applications. The long deep design gives valuable additional reach in tight or obstructed spaces, including situations with protruding threaded rods. Conforming to ISO 2725 part 3 and manufactured from matt chromed chrome-vanadium steel, this socket is built to perform reliably under professional demands. The hexagonal profile ensures firm, accurate engagement with the fastener head, delivering high torque efficiently and reducing wear on bolt edges. A ball intercept ring maintains a secure connection to the 1/2" drive throughout both hand and machine (non-impact) operation. Knurling at the lower end and Wera's Take it easy colour-coding complete a well-considered design.
