Combination wrench Proline 20 mm, model 35420, length 238 mm, 1 piece

Proline combination wrench 20 mm, model 35420, is a single-piece hand tool with a total length of 238 mm designed for tightening and loosening hex nuts and bolts. The wrench integrates an open-end on one side and a ring-end on the other, enabling access to fasteners in a range of positions. Its cold-forged construction and ground heads ensure dimensional accuracy and reliable engagement with fastener faces, while the chromium-plated finish protects against corrosion and simplifies cleaning.

Advantages

The cold-forged steel body provides high strength and durability, reducing the risk of bending under torque. Ground heads deliver precise fit to nut and bolt profiles, minimising rounding and slippage during use. The chromium-plated surface resists rust and abrasion, extending service life and maintaining a consistent appearance over time. The combination of open and ring ends offers versatility for both quick adjustments and higher-torque applications.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Household repairs and DIY projects
• Workshop and professional tool kits

How to use

Select the 20 mm end that best fits the fastener and place it squarely on the nut or bolt head to ensure full contact across flats. Use the open-end for quick turning in accessible locations and the ring-end when higher torque or better grip is required. Apply steady force aligned with the wrench axis to avoid rounding the fastener. After use, wipe the tool clean and store it in a dry toolbox or on a rack to preserve the plated surface.

Usage recommendations

For safe operation, inspect the wrench for damage or wear before use. Avoid using cheater pipes or extensions that exceed the tool’s intended leverage, and do not use the wrench as a hammer or pry bar. Regularly clean and lightly oil the tool to maintain the chromium finish and prevent corrosion.
