The Wera 8790 HMB Zyklop 3/8" Drive Hexagon Socket is available here in a 7/8" socket size — the largest in the range — making it the go-to choice for heavy-duty applications involving large external hexagon bolts and screws in plant, agricultural, and industrial settings. Compliant with ISO 2725 part 3, this socket is built for both manual and power tool (non-impact) use, ensuring it can be deployed across a wide variety of tasks and drive tools without compromise. The knurled lower end provides a firm, slip-proof grip when positioning the socket by hand, and the ball stop groove ensures secure retention on the 3/8" drive — both important features when working with larger, higher-torque fasteners. Wera's 'Take it easy' colour-coding system completes the package, allowing fast and accurate identification within a full socket set.
