Combination Wrench Wera 05020204001

The Wera 05020204001 Combination Wrench (13 mm, 160 mm) is a single-piece hand tool designed for reliable screwdriving in confined and obstructed work areas. It combines a pivoted open mouth with a slim ring end to allow access where straight wrenches cannot reach, and its corrosion-resistant finish increases service life for workshop and field use.

Advantages

The 7.5° pivoted mouth together with a double-hexagon geometry increases the number of placement points, allowing the wrench to engage fasteners every 15°. Repeating a 180° rotation around the tool’s longitudinal axis gives four usable positions for working in narrow spaces. The slim, robust ring side is angled 15° to the tool axis to improve access, and a high-quality surface treatment provides long-lasting corrosion protection. The tool includes Wera’s Take it easy colour coding for quick size identification.

Suitable for (tasks / use cases)

• Working in confined or obstructed spaces where access is limited
• Mechanical maintenance and repair on vehicles, machinery, and equipment
• Assembly and disassembly tasks requiring precise placement and repeatable engagement
• Home workshop and professional service environments

How to use

Select the 13 mm Wera combination wrench for the corresponding fastener. Position the pivoted open mouth or the angled ring on the bolt or nut, and if space is tight, rotate the wrench 180° around its longitudinal axis to access one of the four placement positions. For minimal clearance, use the mouth’s repeated 180° turns to engage the fastener every 15° until the desired rotation is achieved. Apply steady force aligned with the tool to avoid slipping; use the ring end for final tightening or loosening where a full encirclement of the fastener is possible.

Usage recommendations

Use the wrench within its intended size (13 mm) and avoid applying excessive torque beyond hand tool limits. Keep the tool clean and occasionally inspect the surface finish; reapply corrosion protection if needed. Use appropriate personal protective equipment when working on machinery or vehicles.
