Wrenches/Sockets Wera Joker 05073277001

Wera Joker 17 mm combination wrench with ratcheting ring end and holding function. The tool is made from chrome molybdenum steel with a nickel-chrome coating for corrosion protection. It has a replaceable, extra-hard metal plate in the open jaw that grips nuts and bolts, an integrated limit stop to prevent slipping around the bolt head, and a fine-tooth 80-tooth ratchet mechanism in the ring end. The Joker features a double-hex geometry and a 30° return angle at the open end to allow work in confined spaces and to reduce the need to flip the wrench during fastening tasks.

Advantages

The replaceable hardened metal plate in the jaw secures fasteners with hard teeth, reducing the risk of dropping or slipping. The integrated limit stop prevents the wrench from sliding off the bolt head and allows higher torque to be applied safely. Double-hex geometry ensures a positive connection with nuts and bolts while the 30° return angle and 80-tooth ratchet provide flexibility and efficient operation in tight spaces. Nickel-chrome finish and chrome molybdenum steel construction improve strength and corrosion resistance.

Suitable for

• Assembly and maintenance of machines and equipment where space is limited
• Working with hex nuts and bolts requiring reliable holding and higher torque
• Service and repair work on plumbing fittings and pipe connections
• Tasks where dropped fasteners are a risk and holding function improves efficiency

How to use

Place the open jaw over the nut or bolt so the replaceable metal plate holds the fastener in position, or engage the ratcheting ring end on the fastener head. Use the integrated limit stop to prevent slipping and apply torque as required. When working in confined spaces, use the 30° return angle to reposition the wrench with minimal movement. Replace the hardened jaw plate if worn to maintain the holding function.

Usage recommendations

Use the appropriate size (17 mm) for the fastener and inspect the replaceable metal plate regularly for wear. Store the wrench in the colour-coded Wera tool finder system to quickly identify the correct profile and size.
