Wera 020331 Joker M/L Self-setting Double Spanner
Self-setting double spanner for hexagon screw heads and bolts with wrench sizes 13-16 mm and 16-19 mm (metric) or 1/2″-5/8″ and 5/8″-3/4″ (imperial)
With its continuous and parallel jaws, the tool replaces several single spanner sizes
Required size is automatically and continuously set when attaching the tool to the hexagon bolt or screw
Integrated lever mechanism securely clamps the hexagon screw or bolt between the jaws, which significantly reduces the risk of slippage or damage
Ratchet feature ensures fast and consistent screwdriving without removing the tool
By using the corner-width rectangular prisms, a return angle of only 30° can be achieved
Ratchet feature and corner-width prism make it possible to work even in confined spaces
