Ring Spanner (Double-Ended) Proxxon 20 x 22 mm

Proxxon double-ended ring spanner 20 x 22 mm is a compact hand tool designed for tightening and loosening hexagonal nuts and bolts. Each end features a closed ring profile that surrounds the fastener head to provide a secure grip and reduce the risk of rounding. The wrench is intended for tasks that require precision and reliable torque transfer in mechanical, automotive and household maintenance contexts.

Advantages

The double-ended design provides two commonly used metric sizes in a single tool, saving space in a toolbox and reducing the need to switch tools. Closed ring ends ensure even force distribution around the fastener to minimise slippage and damage. The compact length allows access in confined spaces and the solid metal construction offers durability for repeated use under workshop conditions.

Suitable for

• Automotive repairs and routine maintenance
• Mechanical assembly and disassembly tasks
• Household maintenance and appliance servicing
• Workshop jobs where access is limited and secure grip is required

Key specifications

• Ring sizes: 20 mm and 22 mm
• Double-ended closed-ring configuration
• Material: high-strength forged steel (surface finish may vary)
• Compact length suitable for tight spaces
• Designed for use with hexagonal nuts and bolt heads

How to use

Select the correct ring end that matches the nut or bolt size (20 mm or 22 mm). Place the closed ring fully over the fastener head so the wrench seats evenly against all sides of the hexagon. Apply steady torque using the handle, keeping the tool aligned with the fastener axis to avoid side loading. For stubborn or rusted fasteners, use controlled force and consider applying penetrating lubricant first. Avoid using excessive impact force on the wrench to prevent tool or fastener damage.

Usage recommendations

For reliable performance, inspect the ring surfaces before use and replace the wrench if any deformation or excessive wear is evident. Use the 20 x 22 mm double-ended ring spanner together with standard workshop safety practices, including eye protection and gloves when appropriate. Store the tool in a dry place to limit corrosion and keep the ring faces clean for best grip.
