Ring spanner Proxxon 23935, 36 mm, closed-end wrench for hex nuts

Proxxon 23935 is a 36 mm ring spanner engineered for secure engagement with hexagonal nuts and bolts. The closed-end design ensures full contact with fastener heads to minimise rounding and maximise torque transfer. Built for professional and hobby use, this hand tool is intended for tasks that require precise, robust turning force in tight or exposed locations.

Advantages

The closed 36 mm ring profile provides even force distribution across the nut or bolt head, reducing wear on fasteners. Manufactured to Proxxon quality standards, the spanner offers a rigid body that resists bending under load and a smooth finish that helps prevent corrosion. Its size and ring construction deliver reliable torque transmission and improved grip compared with open-end wrenches.

Suitable for

• Automotive repair and maintenance where 36 mm fasteners are used
• Mechanical assembly and disassembly of machinery
• Industrial maintenance and service tasks
• Workshop and garage manual tightening or loosening of hex nuts and bolts

Key specifications

• Working size: 36 mm
• Type: closed-end ring spanner for hexagonal fasteners
• Material characteristics: hardened and finished metal for strength and wear resistance
• Contact style: full-contact ring profile for reduced rounding and improved torque transfer
• Hand tool category: single-piece manual wrench designed for manual turning

How to use

Place the ring spanner over the hexagonal nut or bolt head so the ring fully encloses the fastener. Apply steady, controlled force in the required direction to tighten or loosen the fastener. Use the full contact surface of the ring to avoid slipping; if higher torque is needed, ensure the tool is correctly seated and apply force gradually. Inspect the spanner and the fastener before use to confirm correct fit and absence of damage.

Usage recommendations

For safe and effective use, select the correct 36 mm spanner for the fastener, keep the tool clean and free of oil for secure grip, and avoid using cheater bars or excessive impact force which could damage the tool or fastener. Store in a dry place to preserve the finish.
