Socket Wera 8790 HMC

The Wera 8790 HMC is a long 1/2" hand and machine socket (ISO 2725 part 3) with a ball intercept ring, designed for external hexagonal bolts and sockets. It is suitable for manual and non-impact machine operation, including work with low-lying screw heads and protruding threaded rods. The socket features Wera's Take it easy tool finder colour coding for quick size identification and an easy-to-grip surface that performs well even with oily hands. Its hexagon profile allows transmission of high torque while reducing wear on bolt and screw edges; a fine-toothed ratchet return angle makes a double hexagon profile unnecessary, especially in confined spaces.

Advantages

The long 1/2" design provides better reach for recessed fasteners while the ball intercept ring secures the socket on the fastener or extension. Colour coding speeds up tool selection on the workbench. The hexagon geometry transfers high forces efficiently and minimises rounding of bolt heads. The grip-friendly surface improves handling in oily or greasy conditions. Built to ISO 2725-3 standards, the socket is compatible with common hand and machine drives (non-impact).

Suitable for

• Servicing and assembly of machinery using external hex bolts
• Work with low-lying screw heads or protruding threaded rods
• Workshop and professional maintenance where non-impact machine operation is required
• Tasks requiring extended reach into recessed or hard-to-access fasteners

How to use

Fit the socket onto the 1/2" drive ratchet, extension or machine adaptor and engage it onto the external hex fastener until the ball intercept ring secures the socket. Use manual or non-impact machine drives only, avoiding impact tools. Position the ratchet or machine square with the fastener and apply torque steadily. For tight access areas, use the socket's extra length to reach recessed heads; the fine-toothed ratchet return angle allows small movements to advance or loosen fasteners in confined spaces.

Usage recommendations

Use the Wera 8790 HMC with compatible 1/2" ratchets or machine adaptors and avoid impact wrenches. Select the correct colour-coded size using the Take it easy marking to ensure a secure fit. Regularly inspect the socket for wear and avoid using damaged sockets to prevent fastener damage.
