The wera 6001 joker switch wrench in 12mm is one of the most commonly used sizes across automotive, plumbing, and general engineering trades. At 171mm in overall length, it delivers a confident grip and excellent torque transfer. The exchangeable metal jaw plate keeps 12mm fasteners firmly in place during use, significantly reducing the risk of dropping nuts and bolts in hard-to-reach areas. The integrated limit stop locks the wrench onto the bolt head, enabling higher torque without slippage. The double-hex geometry provides a secure bite, and the 30 jaw return angle speeds up repetitive fastening. The 80-tooth reversible ring ratchet ensures smooth, precise operation in confined spaces. Forged from high-performance chrome-molybdenum steel with a nickel-chromium coating for superior corrosion protection and long-term reliability. Colour coded by size.
