2-piece set. Self-adjusting double ring wrench for hexagonal screw heads and screws with sizes 7-10, 10-13 (metric) or 1/4"-3/8", 7/16"-5/8" (imperial) as well as 13-16, 16-19 (metric) or 1/2"-5/8" and 5/8"-3/4" (imperial). With its continuous and parallel jaws, the tool replaces multiple individual ring wrench sizes. The required size is automatically and continuously adjusted when the tool is applied to the hex screw or bolt. The integrated lever mechanism securely clamps the hex screw or bolt between the jaws, significantly reducing the risk of slipping or damage. The ratchet function allows for quick and smooth screwing without the need to remove the tool. By using the angular rectangular prisms, a return angle of just 30° can be achieved. The ratchet function and the angular prism enable work even in tight spaces. The adjustable Joker 6006 double ring wrench with ratchet function is the universal screwing tool. Self-adjusting. Gripping. Clamping. In a robust case.
