Wrenches/Sockets Wera Joker 10 mm

The Wera Joker 10 mm ratcheting combination wrench is a single-piece tool forged from high-performance chrome molybdenum steel with a nickel-chrome finish for corrosion protection. It combines an open jaw with a ratcheting ring end, an exchangeable hardened metal plate in the jaw for a holding function, a double-hex geometry and an integrated limit stop. The tool is 159 mm long and designed for reliable strength and long service life in professional and DIY applications.

Advantages

The replaceable hardened metal plate in the jaw secures nuts and bolts by biting into them with extra-hard teeth, reducing the risk of dropping or slipping. The integrated limit stop prevents slipping around the bolt head and allows higher torque to be applied safely. Double-hex geometry ensures a positive connection with fasteners and a reduced risk of rounding. The open end has a 30° return angle to minimise flipping, while the ring end houses an 80-tooth fine-tooth ratchet mechanism for flexibility in confined spaces. The forged geometry and chrome-molybdenum material provide high torque transfer and durability. Colour-coding aids quick tool identification.

Suitable for

• Loosening and tightening nuts and bolts in confined spaces
• Work requiring a holding function to position fasteners before threading
• Applications needing higher torque without slipping or rounding
• Professional workshops and DIY repair tasks

How to use

Place the open jaw over the nut or bolt and, if required, use the jaw holding function to secure the fastener in the mouth before positioning it on the thread. For confined spaces or continuous turning use the ring end ratchet; select the required turning direction and operate with short strokes thanks to the 80-tooth mechanism. To change the replaceable metal plate, remove the plate per the manufacturer's instructions and fit the replacement plate securely. Apply force through the wrench shaft with steady pressure while keeping the limit stop engaged against the fastener head to reduce slipping.

Usage recommendations

Use the Wera Joker 10 mm for tasks where fastener retention, reduced flipping and higher applied torque are needed. Inspect the replaceable jaw plate for wear and replace when tips are worn to maintain holding performance. Avoid using the wrench on damaged or severely rounded fasteners.
