Wera 6004 Joker 2 Set Self-Setting Open-End Wrench Set (2-Piece)

The Wera 6004 Joker 2 Set is a professional self-setting open-end wrench set designed for efficient and damage-free tightening of hexagonal nuts and bolts. This 2-piece set covers both metric and imperial sizes, featuring a unique self-setting mechanism that automatically adjusts to the fastener size, eliminating the need for manual adjustment. The chrome-molybdenum steel construction with nickel-chrome plating ensures durability and corrosion resistance. The ergonomic multi-component handle provides a comfortable grip, while the 30° return angle and ratcheting function enable fast and precise work. The set includes two wrenches: one covering 10-13 mm (3/8" - 1/2") and the other covering 16-19 mm (5/8" - 3/4"), both with parallel smooth jaws to prevent fastener damage. Supplied in a robust textile pouch for convenient storage and transport.
