Open-end ratchet wrench Proxxon PR23246 12x13 mm, dual-size hand tool

Proxxon PR23246 is an open-end ratchet wrench that combines two metric jaw sizes — 12 mm and 13 mm — in a single compact hand tool. The dual-size design allows fast switching between adjacent fastener sizes without changing tools. The ratcheting action integrated into the open end provides reversible tightening and loosening in confined spaces where a full socket set or long handle cannot be used. The tool is intended for manual use in general mechanical, automotive and household maintenance tasks.

Advantages

The compact dual-head layout reduces clutter and the need to carry multiple wrenches while covering two commonly used metric sizes. An internal ratchet mechanism in the open end enables incremental turning without repositioning the wrench, which saves time on repetitive jobs and in tight clearances. The one-piece construction offers tactile feedback and controlled torque transfer for hand-operated fastening tasks, and the slim profile improves access to recessed or closely spaced nuts and bolts.

Suitable for

• Automotive repair and under-hood work where space is restricted
• General mechanical assembly and maintenance
• Household repairs and appliance maintenance
• Bicycle and small-engine servicing

Key specifications

• Open-end sizes: 12 mm and 13 mm
• Ratcheting action integrated into the open end for reversible operation
• Hand-operated compact wrench for confined spaces
• Durable metal construction suitable for repeated use
• Slim profile for improved access to tight fasteners

How to use

Position the appropriate jaw (12 mm or 13 mm) over the nut or bolt head, ensuring full seating to avoid rounding the fastener. Use the ratchet direction to select tightening or loosening and apply steady manual force to turn the fastener. For best control, work with short strokes in confined areas and re-seat the wrench if slippage is detected. Do not use the wrench with cheater bars or pneumatic tools; it is designed for hand operation only.

Usage recommendations

Inspect fastener fit before applying force and keep the wrench clean of oil and debris to maintain reliable ratcheting function. Use the correct jaw size to minimize wear on both the tool and fastener. Store in a dry place to prevent corrosion and check periodically for signs of wear or damage before use.
