Combination wrench YATO YT-0337, 8 mm, steel, metallic finish, length 130 mm

YATO YT-0337 is a single 8 mm combination wrench made from steel with a metallic finish. Its overall length of 130 mm and compact profile make it suitable for work in confined spaces while providing the leverage required for tightening and loosening hex fasteners. The tool combines an open-end jaw on one side and a 12-point box end on the other to address a variety of mechanical fastening tasks.

Advantages

The wrench is manufactured from steel for strength and wear resistance and finished with a metallic surface treatment to resist corrosion and simplify cleaning. The dual-end design—open jaw and 12-point box—offers flexibility for working on fasteners in different positions and reduces the need to change tools frequently. Its 130 mm length and slim cross-section provide easier access in narrow gaps and overhead applications.

Suitable for

• Automotive repairs and maintenance
• Assembly and disassembly of mechanical components
• General workshop and household repair tasks
• Toolkits for technicians, electricians, and mechanics

How to use

Select the 8 mm side of the combination wrench and place the open jaw or box end onto the hex fastener. Apply steady torque in the required direction, keeping the wrench aligned with the fastener to avoid rounding. For fasteners in tight spaces, use the slim profile and shorter length to maneuver the tool into position; for higher torque requirements, use the box end engagement where possible. Inspect the wrench for wear or damage before use and avoid applying excessive force beyond the tool’s intended capacity.

Usage recommendations

Use the wrench with compatible 8 mm hex fasteners only. Keep the tool clean and dry after use and store it in a dedicated slot in a toolkit or on a rack to prevent corrosion and mechanical damage. For safety, wear appropriate hand protection when working with high torque or in contaminated environments.
