Wera 6004 Joker Self-Setting Spanners

The Wera 6004 Joker Self-Setting Spanners are single tools that automatically adjust to a wide range of metric and imperial sizes.

These universal spanners can be used for both multiple metric and imperial sizes, making it possible to use a single tool for the widest range of applications. The spanners automatically adjust to different fixing sizes, the continuous and parallel jaws replacing several single spanner sizes.

The tools have an integrated lever mechanism that securely clamps the fixing between the jaws, significantly reducing the risk of slipping or damage. The ratchet function ensures fast and consistent use without removing the tool and, thanks to the corner-width rectangular prisms, a back-pivoting angle of only 30° can be realised. The single-arm design in conjunction with the ratchet function and the corner-width prism make it possible to work even in confined spaces.
