Combination wrench set YATO YT-0800 — 17, 19, 21, 22 mm, chromium‑vanadium steel, metallic finish

YATO YT-0800 is a set of combination wrenches in sizes 17, 19, 21 and 22 mm manufactured from chromium‑vanadium steel with a metallic finish. Each wrench integrates an open-end and a boxed end to provide flexible engagement with bolts and nuts. The design focuses on mechanical strength, accurate fit and corrosion resistance to meet the needs of automotive, mechanical and general maintenance tasks.

Advantages

The chromium‑vanadium steel construction ensures high tensile strength and wear resistance while the metallic finish adds a protective layer against surface corrosion. The combination of open and boxed ends allows quick repositioning and secure torque application, reducing rounding of fasteners. The set covers commonly used metric sizes, enabling efficient work on a range of vehicles and equipment without the need for adapters.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• General workshop and garage tasks
• Home DIY projects involving metric fasteners

Key specifications

• Sizes: 17 mm, 19 mm, 21 mm, 22 mm
• Material: chromium‑vanadium steel
• Finish: metallic (chrome-like protective surface)
• Type: combination wrench (open-end and boxed end per piece)
• Typical applications: torque transfer on bolts and nuts in mechanical and automotive contexts

How to use

Select the correctly sized wrench for the bolt or nut to ensure full face engagement. Use the open-end for quick access in confined spaces or when sliding onto a fastener, and switch to the boxed end for higher torque and reduced risk of rounding. Apply steady, controlled force and avoid sudden impacts that exceed the tool’s intended static torque capacity. After use, inspect contact faces for wear and wipe the tools clean to maintain the metallic finish.

Usage recommendations

Store the wrenches in a dry environment to preserve the metallic finish and periodically apply light oil if used in corrosive conditions. For safety and longevity, do not use these combination wrenches as pry bars or striking tools; use torque-limited tools where precise torque settings are required.
