Wrench, PARTNER 17 mm combination (open-ring) L=210 mm, Cr-V steel

Combination wrench PARTNER 17 mm, 210 mm long, made from Cr-V (chromium-vanadium) steel. The tool has an open (flat) jaw on one end and a ring (box) end on the other, providing two grip types in a single hand tool. Its 17 mm size and 210 mm overall length balance reach and leverage for common fastening tasks in automotive, household and workshop environments.

Advantages

The chrome-vanadium construction offers enhanced strength and wear resistance compared with standard carbon steels, while the dual-end design allows rapid switching between open and ring engagement without changing tools. The 210 mm length provides improved torque for tightening and loosening bolts and nuts, and the slim profile of the open jaw helps access confined spaces. The ring end ensures a secure multi-point grip to reduce rounding of fasteners.

Suitable for

• Automotive repairs and maintenance
• Household plumbing and fixture adjustments
• Assembly and disassembly of machinery and equipment
• General workshop and garage tasks

Key specifications

• Wrench type: combination (open-ring)
• Size (nominal): 17 mm
• Overall length: 210 mm
• Material: chromium-vanadium (Cr-V) steel
• Finish: typically polished or chrome-plated for corrosion resistance
• Ring end: enclosed multi-point grip for secure fastening
• Open end: slim profile for access to confined spaces

How to use

Position the appropriate end of the wrench over the nut or bolt head and ensure full contact before applying force. Use the ring end when a secure multi-point grip is required to minimise rounding; use the open end where access is limited or where you need to slide the wrench onto fasteners from the side. Apply steady, controlled force and avoid sudden impacts. For higher torque needs, select a longer wrench or use proper torque tools rather than applying excessive force to this hand tool.

Usage recommendations

Keep the wrench clean and free of oil or debris to maintain grip and safety. Inspect the tool periodically for wear or deformation, and replace if the jaws or ring show rounding or cracks. Store in a dry place to prevent corrosion and consider using a wrench set with sizes matching common fasteners for efficient work.
