Box end wrench KS Tools 517.0818, chromium-vanadium steel, 30x32 mm, 357 mm length

KS Tools 517.0818 is a single-piece box end wrench manufactured from chromium-vanadium steel with a polished chrome finish. The double ring spanner features two closed ends sized for 30 and 32 mm fasteners and a length of 357 mm, providing a balance between reach and leverage for working on larger nuts and bolts. This tool is made in Germany and weighs approximately 660 g, designed for reliable torque transfer and a secure grip in automotive, industrial and maintenance environments.

Advantages

The chromium-vanadium steel construction offers high strength and wear resistance while the chrome plating protects against corrosion and facilitates cleaning. The double ring design and offset profile improve access to recessed or closely spaced fasteners, and the single-piece construction ensures consistent alignment and efficient torque transmission. The 357 mm length provides extra leverage for loosening or tightening large fasteners without excessive hand fatigue.

Suitable for

• Automotive repair and wheel nut work on cars and light commercial vehicles
• Industrial machinery maintenance and assembly
• Heavy equipment maintenance where 30 mm and 32 mm fasteners are used
• Workshop and garage applications requiring high-strength hand tools

How to use

Select the appropriate ring end (30 mm or 32 mm) and position the closed end squarely over the nut or bolt head to ensure full contact. Apply steady force to the handle for loosening or tightening, keeping your wrist aligned with the tool to reduce the chance of slipping. For confined spaces, use the offset orientation to clear nearby obstacles and reposition the wrench as needed using incremental turns. Inspect the fastener seating before applying maximum torque to avoid rounding corners.

Usage recommendations

For safe and effective use, avoid striking the wrench with a hammer or using it with cheater bars beyond recommended leverage. Keep the chrome finish clean and dry after use to limit corrosion. Use the wrench within its intended size range and inspect for signs of wear or deformation before each use.
