Wrench Proxxon 18 mm flat-ring hand spanner Proxxon MicroSpeeder PR23267

Proxxon MicroSpeeder 18 mm flat-ring hand spanner is a single-piece tool designed for manual tightening and loosening of hexagonal nuts and bolts. The compact, flat-ring design provides access in confined spaces and allows precise torque application during mechanical, automotive and hobby tasks. Manufactured to Proxxon quality standards, this 18 mm spanner is intended for workshop use, maintenance and precision repair jobs where a slim, reliable wrench is needed.

Advantages

The flat-ring profile combines the reach of an open spanner with the secure engagement of a ring end, reducing the risk of rounding fasteners. Single-piece construction increases durability and ensures consistent performance under repeated manual use. The compact geometry and thin head thickness improve accessibility to recessed or closely clustered nuts. The tool is suitable for operations requiring a robust, straightforward 18 mm solution without additional adapters.

Suitable for

• Tightening and loosening 18 mm hex nuts and bolts
• Automotive maintenance and repair in confined engine or chassis areas
• Precision mechanical assembly and disassembly
• Hobby projects, model building and small workshop tasks

Key specifications

• Nominal size: 18 mm working profile
• Type: flat-ring (combination of open and ring ends in a slim one-piece design)
• Construction: single-piece hand spanner for manual use
• Geometry: thin head for access in narrow or recessed locations
• Intended use: tightening and loosening hexagonal fasteners by hand

How to use

Select the 18 mm flat-ring end that matches the fastener. Position the ring over the nut or bolt head so the contact surfaces align, and apply steady manual force to turn clockwise to tighten or counterclockwise to loosen. For best control, maintain full seating of the ring on the fastener and avoid excessive leverage that exceeds the tool's intended manual use. Use in combination with appropriate lighting and clearance assessment when working in tight spaces.

Usage recommendations

For safe and long-lasting performance, keep the spanner clean and free of oil or debris on contact surfaces, check fastener fit before applying force, and avoid using the tool with hammers or extensions that could overstress the single-piece construction.
