Wrenches/Sockets Wera Joker 05073273001

The Wera Joker 13 mm combination wrench (MPN 05073273001, EAN 4013288164377) is a single-piece ratcheting wrench made from chrome-molybdenum steel with a nickel-chrome finish. It combines an open jaw with a ring-end ratchet and a replaceable hardened metal plate in the jaw that holds nuts and bolts securely. The wrench features a double-hex geometry, an integrated limit stop and an 80-tooth fine-tooth ratchet at the ring end, designed for reliable fastening in confined spaces and high torque transfer.

Advantages

The replaceable hardened metal plate in the jaw secures fasteners and reduces the risk of dropping or slipping. The integrated limit stop prevents the wrench from slipping off the bolt head and permits higher torque application without using the thumb as a depth stop. Double-hex geometry and the hardened gripping plate provide a positive connection and improved bite into fasteners. A 30° return angle at the open end reduces the need to flip the wrench, while the 80-tooth ratchet at the ring end offers fine-step operation in tight areas. Nickel-chrome coating improves corrosion resistance and the forged chrome-molybdenum construction ensures high strength.

Suitable for

• Positioning and fastening nuts and bolts where a holding function is required
• Work in confined or tight spaces where small return angles and fine ratchet steps are needed
• Applications requiring higher torque and reduced risk of slipping
• General mechanical, maintenance and assembly tasks using 13 mm fasteners

How to use

Place the open jaw or ring end over the 13 mm nut or bolt so that the replaceable metal plate engages the fastener. Use the holding function to secure the nut or bolt in the jaw, position it on the threaded part, then tighten or loosen using the ratchet at the ring end or the open end as required. For confined spaces use the ring-end ratchet’s fine 80-tooth mechanism to work with minimal movement. Replace the hardened plate when worn to maintain secure holding performance.

Usage recommendations

Inspect the hardened jaw plate and ratchet before use; replace the plate if tips are worn. Apply force along the wrench axis, avoid sideways bending, and keep the nickel-chrome finish clean to prolong corrosion protection. Use the 13 mm Wera Joker for suitable fasteners only and follow workplace safety procedures when applying high torque.
