Combination Wrench Wera 05020203001

The Wera 05020203001 combination wrench is a single-piece 12 mm tool designed for use in confined workspaces. Its Joker 6003 mouth geometry combines a 7.5° pivoted open jaw with a double hexagon profile to increase placement points and enable working on bolts and screw heads in tight positions. The slim, robust ring side is angled by 15° to the tool axis and the surface is treated for long-lasting corrosion protection. The wrench measures 148 mm in length and uses Wera's Take it easy colour coding by size to speed up tool selection.

Advantages

The unique mouth geometry doubles the possible placement points and allows taking bolts every 15°, while a 180° rotation around the longitudinal axis provides four placement options. The tool's single-piece design ensures stable torque transfer and durability. A high-quality surface treatment improves corrosion resistance, and the angled ring side facilitates access in narrow spaces. Colour coding by size simplifies identification in a toolbox.

Suitable for

• Tight and confined spaces where standard wrenches have limited access
• Maintenance and repair tasks on machinery and equipment with restricted clearance
• Automotive and bicycle repair requiring precise placement on small fasteners
• General fastening and loosening of 12 mm nuts and bolts in workshops and on-site jobs

How to use

Place the open or ring end on the 12 mm nut or bolt head and ensure full seating before applying torque. For work in narrow spaces, take advantage of the Joker 6003 mouth: pivot and rotate the wrench around its longitudinal axis in 180° increments to access different placement points, and fine-adjust placement in 15° steps if needed. Use the angled ring side to reach fasteners where a straight wrench would not fit. Apply steady, controlled force to avoid slipping or rounding the fastener.

Usage recommendations

Use the colour coding to quickly identify the 12 mm wrench among other sizes. Inspect the wrench for wear or damage before use and avoid applying impact forces not intended for hand wrenches. Clean and store the tool dry to preserve the corrosion protection.
