Socket Wera 8790 HMC

The Wera 8790 HMC is a 1/2" drive hand and machine socket (ISO 2725‑3) with a ball intercept ring, designed for external hexagonal bolts and nuts. Intended for manual and machine use (non‑impact), it works well in confined spaces, with low‑lying screw heads and with protruding threaded rods. The socket includes Wera's Take it easy tool finder with colour coding by size and a textured surface that improves grip even with oily hands. The hexagon profile transmits high torque while reducing stress on bolt edges; coupled with a fine‑toothed ratchet, it is suitable for applications requiring small return angles.

Advantages

Durable construction from a professional manufacturer ensures reliable performance in workshop and industrial environments. The ball intercept ring secures the socket on the fastener for safer handling during machine and hand operations. Colour coding by size speeds up tool selection, and the textured grip improves handling in slippery conditions. The hexagon profile maximises torque transfer and minimises rounding of bolt heads, while the fine‑toothed ratchet compatibility allows operation in tight spaces.

Suitable for

• Manual and non‑impact machine tightening and loosening of external hex bolts and nuts
• Work in confined spaces or on low‑lying screw heads
• Applications with protruding threaded rods
• Professional workshop, maintenance and assembly tasks

How to use

Select the appropriately sized Wera 8790 HMC socket using the colour coding. Push the socket onto the fastener until the ball intercept ring engages to secure the fit. Use with a compatible 1/2" drive ratchet or machine (non‑impact) and apply torque smoothly. For work in restricted spaces, employ a fine‑toothed ratchet to take advantage of the small return angle. After use, clean off debris and lightly oil to protect the socket from corrosion before storage.

Usage recommendations

Do not use the socket with impact tools. Choose the correct metric socket size to avoid rounding bolt heads; if resistance is high, verify fastener condition and use appropriate torque rather than excessive force.
