Wrenches/Sockets Wera Joker 05073276001

The Wera Joker 05073276001 is a 16 mm ratcheting combination wrench 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 and features an exchangeable hardened metal plate in the jaw that holds nuts and bolts securely. The tool has compact dimensions (35 mm width, 8.2 mm depth, 212 mm length) and is designed for use in confined spaces where precise, reliable fastening is required.

Advantages

The Joker offers a unique holding function via a replaceable metal plate in the jaw that bites into fasteners to reduce dropping and slipping. An integrated limit stop prevents the wrench from slipping off the bolt head and allows higher torque to be applied safely. The double-hex geometry ensures a positive connection with nuts and bolts, while a 30° return angle at the open end reduces the need to flip the wrench. The ring end ratchet uses a fine-tooth 80-tooth mechanism for flexibility in tight spaces, and the specially forged geometry provides high torque transfer. Nickel-chrome finish increases corrosion resistance and colour coding enables quick tool selection.

Suitable for

• Holding and positioning nuts and bolts during assembly and repair
• Fastening and loosening in confined or hard-to-reach spaces
• Applications requiring higher torque without slipping
• Work where quick tool identification is beneficial (colour-coded set systems)

How to use

Place the open jaw over the nut or bolt and use the jaw holding plate to grip and position the fastener. For higher torque or confined-space work, use the ring end ratchet and select the required direction of rotation. When tightening, ensure the limit stop rests against the fastener head to prevent slipping; when necessary, replace the hardened metal plate in the jaw following the manufacturer’s instructions. Use the 30° return angle at the open end to reposition quickly without flipping the wrench.

Usage recommendations

Use the Wera Joker 16 mm for tasks where secure holding and precise torque application are required. Inspect the exchangeable gripping plate for wear and replace it if tips are rounded to maintain holding function and safety.
