Combination wrench YATO YT-0191 — 10 mm, chrome, chromium-vanadium steel, single piece

YATO YT-0191 is a single-piece 10 mm combination wrench manufactured from chromium‑vanadium steel and finished in chrome. The wrench measures 160 mm in total length, with a head depth of 22.2 mm and a thickness of 7.8 mm. It combines an open-end and a boxed end in a compact tool designed for tightening and loosening bolts and nuts in automotive, mechanical and household repair tasks where corrosion resistance and dimensional stability are required.

Advantages

The single-piece construction eliminates weak joints and provides consistent torque transfer between the handle and the working ends. Chromium‑vanadium steel offers high tensile strength and wear resistance while the chrome finish improves corrosion protection and eases cleaning after use. The 10 mm size and 160 mm length balance access to moderately recessed fasteners with sufficient lever arm for manual torque application. The boxed end delivers secure engagement with hex fasteners to reduce rounding, while the open end allows quick placement on bolts in confined spaces.

Suitable for

• Automotive maintenance and repairs (engine, chassis, brakes)
• Mechanical assembly and disassembly of machinery components
• Household and DIY tasks such as furniture assembly and appliance maintenance
• Workshop use for general fastening and adjustment tasks

Key specifications

• Wrench type: combination (open end + boxed end)
• Size: 10 mm
• Material: chromium‑vanadium steel
• Finish: chrome plated
• Total length: 160 mm
• Head depth: 22.2 mm

How to use

Select the 10 mm end that matches the fastener head. Place the boxed end onto the hex fastener for maximum contact and turn the handle in the desired direction to tighten or loosen. Use the open end when quick repositioning is required or when working in tighter spaces. Apply steady, controlled force and avoid sudden impacts to prevent tool or fastener damage. After use, wipe clean and store in a dry place to preserve the chrome finish.

Usage recommendations

For reliable performance, use the boxed end for final torque to minimize rounding of bolt heads. Avoid using the wrench with cheater bars or as a hammer. Regularly inspect the tool for deformation or excessive wear and maintain storage in a dry toolbox to extend service life.
