Wera 6004 Joker VDE Self-Setting Spanner Range - Wera 05020151001, Wera 05020151001 6004 Joker VDE S Self-Setting Spanner 10-13 x 7/16-1/2" x 155mm - Individually tested tools as per IEC 60900 at 10,000 V for safe working at the approved voltage of 1,000 V. The adjustable VDE spanner continuously and automatically grips all hexagonal sizes in the indicated range of dimensions - metric and imperial. The integrated lever mechanism securely clamps the hexagon screw or bolt between the jaws, which significantly reduces the risk of slippage or damage. The ratchet feature ensures fast and consistent screwdriving without removing the tool. By using the corner-width rectangular prisms, a back-pivoting angle of only 30° can be achieved. The single-arm design, in conjunction with the ratchet feature and the corner-width prism, makes it possible to work even in confined spaces. The adjustable Joker 6004 VDE has a naturally comfortable handle thanks to the 2-component plastic insulation. Safety is
