## Summary description

BOXER combination ring spanner 20 mm (model 31388) is a hand tool combining an open-end wrench and a ring (box) end for engaging hex fasteners. Made for turning nuts and bolts, it provides a secure fit on 20 mm heads and is suitable for automotive, mechanical repair, assembly, and maintenance tasks.

## Long description

BOXER Combination Ring Spanner 20 mm (BOXER 31388) is a dual-ended hand tool that pairs a 20 mm open jaw with a complementary 12-point ring end. Designed for turning 20 mm hex fasteners, it delivers a stable engagement on nuts and bolts for general mechanical, automotive and maintenance tasks.
Advantages
The tool provides two working profiles in one compact piece, allowing quick switching between an open-end grip for accessibility and a ring end for torque and slip resistance. Constructed from hardened alloy steel with a chrome finish, the spanner resists corrosion and wear in workshop environments. Its slim head profile improves access in confined spaces while the 20 mm sizing matches common metric fasteners used on vehicles and machinery.
Suitable for
Automotive repair and routine maintenance on cars, motorcycles and light commercial vehicles
Mechanical assembly and disassembly of equipment using 20 mm hex fasteners
General workshop and industrial maintenance tasks requiring a reliable 20 mm spanner
When it may not be suitable
This combination spanner is intended for manual use and is not designed for impact tools or applications that require power tool torque. It is optimized for 20 mm fasteners; using it on rounded, damaged, or non-metric fasteners may cause slippage or additional wear. For very high-torque applications or where protected jaw contact is required, dedicated socket tools or torque-controlled equipment are preferable.
Key specifications
Working size: 20 mm
Type: combination spanner with open end and ring (box) end
Ring profile: 12-point for engaging hex fasteners
Material: hardened alloy steel with chrome finish
Finish: corrosion-resistant chrome plating
How to use
Select the 20 mm end that best suits the working angle and access. Place the open end over the fastener for quick engagement where clearance is limited, or use the ring end to encircle the fastener head for improved grip and reduced risk of rounding. Apply steady, controlled force in the intended turning direction and avoid sudden impacts. When loosening seized fasteners, work progressively and consider applying penetrating lubricant before attempting high torque.
What to consider before purchase
Ensure the 20 mm size matches the fastener heads you will work with
Confirm manual use is appropriate — this spanner is not rated for impact tools
Check whether a single-ended, angled, or socket alternative is more suitable for confined or high-torque applications
Usage recommendations
Use the ring end when precision and reduced slippage are required; reserve the open end for quick placement in tight spots. Keep the tool clean and store dry to maintain the chrome finish and prevent corrosion. Regularly inspect jaws for wear and avoid applying excessive force that could deform the spanner.
