Wera Joker self-setting Set
The Wera Joker 6004 self-setting set is four ratcheting wrenches (XS through L, covering 7-19mm) whose jaws automatically clamp to metric and imperial fastener sizes, with a lever mechanism that grips the hex to prevent slipping and a 30-degree return angle. Supplied in a 2go-compatible tool bag, it replaces a drawer of single-size spanners for shops and mobile mechanics.
- Joker 6004 replaces several single spanner sizes.
