Socket Wera 8790 HMC

The Wera 8790 HMC Socket is a 1/2" drive, long socket (ISO 2725-3) with a ball intercept ring designed for external hexagonal bolts and nuts. It is suitable for both hand and machine (non-impact) use and works reliably in confined spaces, with low-lying screw heads or on protruding threaded rods. The socket features Wera’s Take it easy colour coding for quick size identification and a grip-friendly surface for handling with oily hands. Its hexagon profile permits high torque transmission while reducing wear on bolt edges; a fine-toothed ratchet makes use in tight spaces efficient thanks to a small return angle.

Advantages

The long 1/2" socket provides secure engagement with external hex fasteners and accommodates machine and manual operation without impact use. Colour coding simplifies fast identification of the required size. A grip-friendly finish improves handling under greasy conditions. The hexagon profile supports high torque transfer and minimizes rounding of bolt corners, while the fine-toothed ratchet compatibility ensures effective operation in limited spaces.

Suitable for

• Servicing and repair of vehicles and machinery
• Assembly and disassembly of hex bolts in tight or recessed areas
• Work on protruding threaded rods and low-lying screw heads
• Professional workshops and advanced DIY projects

How to use

Select the correct socket size using the Take it easy colour coding, attach it to a compatible 1/2" drive ratchet or machine drive (non-impact), and engage the socket squarely on the external hexagon of the bolt or nut. Apply steady torque, keeping alignment between tool and fastener to avoid slipping. For work in confined spaces, use a fine-toothed ratchet to benefit from the small return angle. After use, clean off grime and store the socket in a suitable rack or case to protect the ball intercept ring and finish.

Usage recommendations

Do not use the socket with impact wrenches. For best results, ensure the fastener and socket are free of heavy debris and avoid sudden shock loads to preserve the ball intercept ring and hexagon edges.
