Ring Offset Wrench Proxxon PR23868 5 x 5.5 mm

Proxxon PR23868 is a compact ring offset wrench with dual sizes 5 x 5.5 mm designed for working with small hex fasteners in tight or awkward locations. The offset ring heads and slightly bent profile let the tool reach recessed nuts and bolts while providing reliable contact on the flats to reduce rounding. Manufactured for precision and light workshop use, this wrench is intended for tasks where space is limited and controlled torque application is required.

Advantages

The ring offset shape gives improved access behind components compared with straight open-ended wrenches, allowing use in confined assemblies. Dual-size ends increase versatility by covering two common metric sizes in one compact tool. The closed ring heads provide even force distribution on fastener faces to minimize slippage and damage. Built for precision work, the wrench offers good control for delicate assemblies and repeatable engagement on small hex fasteners.

Suitable for

• Precision mechanics and watch or instrument repair
• Electronics assembly and maintenance
• Bicycle adjustments in tight frame areas
• Model making and hobby workshop tasks
• General light-duty workshop and service jobs

Key specifications

• Sizes: 5 mm and 5.5 mm
• Offset ring head design for improved access
• Dual-ended compact wrench for confined spaces
• Material and finish suitable for precision use
• Intended for small hex fasteners and light-duty torque

How to use

Select the ring end matching the fastener size and place the closed ring fully over the nut or bolt head so the flats seat squarely. Use the offset profile to reach recessed or obstructed fasteners while maintaining steady, controlled torque. Apply force slowly and maintain alignment with the fastener to avoid rounding. When additional leverage is required, position the wrench so the long arm provides mechanical advantage while ensuring the tool remains stable on the fastener faces.

Usage recommendations

Use the 5 or 5.5 mm end appropriate to the fastener to prevent damage; avoid excessive torque beyond light-duty applications. Inspect the wrench and fastener contact before applying force, and keep the tool clean and free of oil or debris to ensure secure engagement. For sensitive assemblies, use cautious, incremental tightening and consider torque-limiting methods if precise torque values are required.
