Wrenches/Sockets Wera Joker 19 mm

The Wera Joker 19 mm combination wrench is a single-piece tool made from high-performance chrome molybdenum steel with a nickel-chrome coating for corrosion protection. It combines an open jaw with a ratcheting ring end, a replaceable hardened metal plate in the jaw that holds nuts and bolts, and a limit stop to prevent slipping around the fastener head. The tool measures approximately 246 mm in length and is colour-coded for quick identification within the Wera "Take it easy" tool finder system.

Advantages

The replaceable metal plate in the jaw secures nuts and bolts with extra-hard teeth, reducing the risk of dropping or slipping. The integrated limit stop prevents the wrench from sliding off the fastener head and allows higher torque to be applied safely. Double-hex geometry ensures a positive fit with fasteners and reduces rounding. The open end has a reduced 30° return angle to minimize flipping during work, while the ring end contains an 80-tooth fine-tooth ratchet mechanism for high flexibility in confined spaces. The forged geometry provides high torque transfer and strength.

Suitable for

• General mechanical assembly and maintenance
• Working in confined spaces where conventional wrenches are difficult to use
• Applications requiring secure holding of nuts or bolts during positioning
• Tasks needing higher torque without slipping or fastener damage

How to use

Place the open jaw over the nut or bolt and use the holding plate to secure the fastener in the jaw for positioning. For fastening or loosening in restricted spaces, use the ring end with the ratcheting mechanism; the 80-tooth fine-tooth ratchet allows small swing arcs. To replace the jaw plate if worn, remove the old plate and install the supplied hardened plate according to the manufacturer's instructions. Use the integrated limit stop to prevent slipping off the fastener head and to apply higher torque safely.

Usage recommendations

Use the Wera Joker 19 mm for precision positioning and high-torque applications in confined spaces. Regularly inspect the replaceable metal plate and ratchet for wear and replace parts as needed to maintain holding and ratcheting performance.
