Open-end and box wrench Proxxon 22 mm PR23271 for mechanical and workshop use

The Proxxon 22 mm combined open-end and box wrench PR23271 is a compact hand tool designed for precise engagement with 22 mm nuts and bolts. Intended for mechanical, automotive and workshop tasks, this single-size wrench integrates an open-end jaw on one side and a boxed, closed ring on the other to offer two common working options in a space-saving form. The tool is constructed for practical use where a reliable 22 mm fit is required for assembly, maintenance and repair operations.

Advantages

This Proxxon 22 mm wrench provides accurate fit and torque transfer to reduce rounding of fasteners. The combination of an open-ended jaw and a box end delivers versatility: the open end allows quick positioning on bolts in tight spots, while the box end offers a more secure grip for higher torque applications. Its compact, single-size design simplifies tool selection and storage for tasks that repeatedly require a 22 mm wrench.

Suitable for

• Tightening and loosening 22 mm nuts and bolts in automotive repair
• Mechanical assembly and disassembly in workshops
• Maintenance and repair of equipment and machinery
• Situations requiring a compact, dedicated 22 mm hand tool

Key specifications

• Size: 22 mm nominal wrench opening
• Type: combined open-end and box (ring) wrench
• Design: single-size, double-ended tool with open and closed ends
• Intended use: manual hand operation for nuts and bolts
• Typical applications: automotive, mechanical, workshop maintenance

How to use

Select the Proxxon 22 mm wrench when working with fasteners specified as 22 mm. Position the open end onto a bolt or nut for quick access and initial turning where space is limited. Use the box end for a more secure engagement when applying higher torque or when the fastener requires full face contact to reduce slippage. Apply steady hand force, avoid sudden impacts, and ensure the tool is correctly seated on the fastener to minimize rounding.

Usage recommendations

For best results, inspect fasteners for dirt or corrosion before use and clean contact surfaces if necessary. Use the box end where possible for final tightening and loosening to protect the fastener; avoid using cheater bars or excessive leverage on the wrench. Store the tool in a dry place to prevent corrosion and check periodically for wear or deformation.
