Socket Wera 8790 HMA

The Wera 8790 HMA is a 1/4" hand and machine socket (ISO 2725 part 3) with a ball intercept ring, designed for use on external hexagonal bolts and nuts. With a length of 50 mm and a compact width of 10.8 mm (approx. 1.18 cm diameter), this metric socket is suitable for manual and non-impact machine operation and offers reliable fit and durability. Made in Taiwan, it features Wera’s Take it easy colour coding for quick size identification and a fine-toothed ratchet compatibility that enables work in confined spaces.

Advantages

The hexagon profile transmits high torque while reducing stress on bolt edges compared with double-hex profiles. The ball intercept ring secures the socket on the fastener or on the square drive, preventing accidental loss. Colour-coded Take it easy tool finder speeds up tool selection. The socket’s compact width and fine-toothed ratchet compatibility allow efficient operation in tight or low-lying screwdriving situations, and its shape is easy to grip even with oily hands.

Suitable for (tasks / use cases)

• Manual screwdriving with a 1/4" drive ratchet or T-handle
• Non-impact machine assembly where precision and compact access are required
• Tight or recessed fasteners and protruding threaded rods
• Workshop, maintenance and service tasks requiring metric sockets

How to use

Fit the socket onto the external hexagonal bolt or nut and tighten or loosen using a manual ratchet, spinner or a non-impact machine tool. For confined spaces, use a fine-toothed ratchet to take advantage of the socket’s small return angle. Remove the socket by depressing the ball ring and pulling the socket from the drive.
