The Wera 6006 Joker 2 Piece Self Setting Double Spanner Set is a professional-grade spanner set designed to replace multiple fixed spanners with just two self-adjusting tools. Each spanner features continuous, parallel jaws that automatically and continuously set themselves to the required size the moment the tool is placed on a hexagon bolt or screw head. This eliminates the need to carry a full set of individual spanners, making the set ideal for tradespeople working across a range of fastener sizes in both metric and imperial applications. An integrated lever mechanism clamps firmly onto the fastener upon engagement, significantly reducing the risk of jaw slippage or rounding of bolt heads — a common issue with conventional spanners. The mechanical ratchet function allows fast, consistent tightening and loosening without removing the spanner between strokes, saving time on repetitive tasks. The corner-width rectangular prisms within the jaw deliver a return angle of just 30°, making these spanners particularly well suited to restricted and confined spaces where swing clearance is limited. Both spanners are supplied in a robust folding pouch with Wera 2go compatibility for organised tool storage and site portability.
