Combination wrench YATO YT-0390, chrome-vanadium steel, sizes 20 mm and 22 mm, 1 pc

YATO YT-0390 is a single-piece combination wrench manufactured from chrome-vanadium steel with a polished stainless finish. The tool integrates an open-end and a boxed-end in one body, covering two adjacent metric sizes — 20 mm and 22 mm — and offers a total tool width of 33.4 mm. It is intended for turning nuts and bolts in automotive, mechanical and general maintenance tasks where a durable, corrosion-resistant hand tool is required.

Advantages

The chrome-vanadium construction provides strength and wear resistance while the stainless polished finish reduces corrosive effects and facilitates cleaning. One-piece design ensures reliable torque transmission and minimizes the risk of joint loosening that can occur with multi-part tools. Dual-size functionality (20 mm and 22 mm) reduces the number of separate wrenches needed in a toolkit, saving space and weight. The combination of open and boxed ends allows access to fasteners in different positions and gives versatility for tightening and loosening operations.

Suitable for

• Automotive repair and routine vehicle maintenance
• Mechanical assembly and disassembly of machinery
• Workshop and garage tasks requiring metric wrenches
• On-site maintenance where a compact, durable tool is needed

• Tool width: 33.4 mm
• Configuration: combination wrench with open and boxed ends
• Quantity: 1 piece

How to use

Select the end (open or boxed) that best fits the fastener and position the wrench so it fully engages the nut or bolt head. Apply steady force in the required direction to loosen or tighten; use the boxed end for higher torque and the open end for quick adjustments or when access is limited. Inspect the contact surfaces for wear or rounding before use and avoid applying impact forces or using the wrench as a hammer. Store the wrench clean and dry to maintain the polished finish and corrosion resistance.

Usage recommendations

For safe and efficient operation, use the 22 mm end for larger fasteners requiring greater torque and the 20 mm end for slightly smaller fittings; avoid excessive force beyond hand torque to prevent tool or fastener damage. Regularly clean and lightly oil the wrench after use in wet or corrosive environments to extend service life.
