Spanner Ring Proxxon 23886, 18×19 mm, set of 4

Spanner Ring Proxxon 23886, 18×19 mm, set of 4 is a compact set of matched ring spanners designed for tightening and loosening hex fasteners in confined and standard working spaces. Manufactured by Proxxon, the set includes sizes optimized for common mechanical and household tasks and delivers controlled torque transfer through full-ring contact with fastener heads. The compact profile of each spanner helps access nuts and bolts where open-ended wrenches cannot reach.

Advantages

The full-ring ends provide secure engagement with fasteners to reduce rounding and slipping. Precision-machined jaws ensure consistent fit on 18 mm and 19 mm hex heads while the compact length improves access in narrow gaps. Durable material and surface treatment resist wear and maintain fit accuracy during repeated use. The set format offers two common metric sizes in a coordinated set for workshop, maintenance, and mechanical use.

Suitable for

• Maintenance and repair of bicycles and small machinery
• Plumbing fixtures and domestic installations
• Workshop and garage mechanical work
• Assembly and disassembly in confined spaces

Key specifications

• Set composition: four ring spanners in matched sizes (18 mm and 19 mm coverage)
• Head type: full-ring (closed) ends for each spanner
• Material: hardened steel with protective surface finish
• Finish: corrosion-resistant coating to extend service life
• Profile: compact length for access to confined areas

How to use

Select the spanner that matches the hex fastener size and place the closed ring over the nut or bolt head until it seats fully. Apply controlled turning force, keeping the spanner aligned with the fastener axis to minimize slippage and rounding. For fastening, turn clockwise; for loosening, turn counterclockwise. When working in tight spaces, position the compact spanner so the body clears nearby obstructions and use steady, incremental turns rather than sudden force.

Usage recommendations

Inspect fasteners for damage before use and ensure the correct size is selected. Avoid using the spanners with cheater bars or hammering, as excessive torque can damage the tool and fastener. Clean and lightly oil the tools after use to maintain the protective finish and prevent corrosion.
