Wera Joker self-setting
The Wera Joker 6004 is a self-setting wrench whose jaws automatically clamp to metric and imperial fastener sizes within each model's range, replacing several fixed spanners. A lever mechanism grips the hex securely to prevent slipping, and a ratcheting action with a 30 degree return angle keeps work fast in tight spaces, suiting mechanics who want fewer tools in the box.
