Extend the functionality of your hand tools with this square adapter from Wera. Thanks to the 1/4-inch hexagonal drive on one end, it lets you fasten standard industrial fixings. Attaching the part is as easy as slotting the 3/8-inch square head at the other end into a compatible socket. It also has a locking pin, which secures it in place when fitted on a machine-operated nut spinner.

• Compatible with all 3/8-inch square drives to work with many different parent tools
• Size is stamped on the shaft, so you know which one to grab

• DIY projects
• Furniture assembly

It only weighs 17g, so your power or hand tool remains easily manoeuvrable.
