The Wera 8790 HMB Deep 3/8" Drive Hexagon Socket in 20mm provides the depth and reach needed for larger hex fasteners in recessed or space-restricted locations. The 64mm length accommodates protruding threaded rods and ensures the socket seats fully and securely on the fastener. ISO 2725 part 3 compliant, this socket is equally capable in manual ratchet use and machine-powered applications (non-impact). The hexagonal profile delivers high, precise torque transmission whilst protecting the fastener head, and knurling on the lower body provides a confident, non-slip grip when positioning by hand — even with oily hands. Wera's 'Take it easy' colour coding ensures the 20mm is immediately identifiable in any socket selection.
