Ring Spanner BOXER 22 mm model 31390 – offset combination wrench, chrome finish

BOXER Ring spanner 22 mm model 31390 is an offset combination wrench designed for tightening and loosening nuts and bolts in mechanical and automotive work. The tool combines a 22 mm closed ring end for a secure, full-contact grip and an open end for rapid placement on fasteners. A chrome finish provides resistance to corrosion and makes the spanner easier to clean after use.

Advantages

The offset angle keeps knuckles clear of flat surfaces and gives better access in confined spaces while the combination of ring and open ends increases versatility for different tightening and loosening situations. The chrome finish improves wear resistance and simplifies maintenance. Solid construction delivers torque transfer with reduced deformation under normal workshop loads.

Suitable for

• Automotive repair and maintenance
• General mechanical assembly and disassembly
• Plumbing and HVAC tasks involving 22 mm fasteners
• Home workshop and DIY repairs requiring a reliable 22 mm wrench

When it may not be suitable

This spanner is a dedicated 22 mm size; it is not suitable for fasteners of other sizes without adapters. It is intended for manual use and normal workshop torque—avoid using it with cheater bars or impact tools, which can damage the tool or the fastener.

Key specifications

• Type: Offset combination wrench (ring and open ends)
• Working size: 22 mm
• Finish: Chrome plated
• Material: High-strength tool steel (factory-specified alloy not listed)
• End configuration: Closed ring end for full-contact grip and open end for quick engagement

How to use

Select the correct 22 mm end for the fastener. For maximum grip and to reduce rounding, place the ring end fully over the nut or bolt and apply steady force, pulling toward the fixed jaw where possible. Use the open end for quick placement or when space prevents fitting the ring end. Work within controlled hand-applied torque limits and reposition the wrench rather than forcing it past its working angle.

What to consider before purchase

• Confirm the fastener size is 22 mm to ensure compatibility
• Check that an offset combination wrench suits the available working space
• Consider material and finish for corrosion resistance if used in humid or corrosive environments

Usage recommendations

Use the ring end for final tightening and loosening to minimize fastener rounding. Avoid extending the handle with pipes or using the spanner with impact tools. Store the spanner clean and dry to maintain the chrome finish and inspect regularly for wear or deformation.
