Proxxon flat wrench 18 x 19 mm PR23846

The Proxxon flat wrench 18 x 19 mm PR23846 is a compact, double-open-end hand tool designed for manual tightening and loosening of hex nuts and bolts. It combines two commonly used sizes—18 mm and 19 mm—in a single slim profile wrench that fits into narrow spaces and standard workshop environments. The wrench is intended for general repair, mechanical maintenance and assembly tasks where a reliable flat wrench is required.

Advantages

This Proxxon flat wrench provides two sizes in one tool, reducing the number of separate wrenches needed in a toolkit. Its slim, flat design allows access to confinements and tight clearances where bulkier tools cannot reach. The open-end heads are shaped for stable contact with fastener flats, helping to minimise slipping and rounded corners during manual torque application. The tool is manufactured to workshop standards suitable for regular use in maintenance, automotive and household settings.

Suitable for

• Tightening and loosening 18 mm and 19 mm hex nuts and bolts
• Mechanical repairs on machinery and equipment
• Automotive maintenance tasks requiring manual wrenches
• Assembly work and general home workshop projects

Key specifications

• Open-end sizes: 18 mm and 19 mm
• Tool type: flat, double open-end wrench
• Design: slim profile for access in narrow spaces
• Material and finish: workshop-grade metal construction with durable surface treatment
• Hand operation: manual torque application, no ratchet mechanism

How to use

Select the end that correctly matches the fastener size and place the open jaw fully onto the flats of the nut or bolt. Apply steady, controlled force to turn the tool in the required direction; for higher torque, position the wrench so force is applied along the handle axis to avoid slipping. If access is limited, use the slim profile to reach the fastener from an angle. After use, clean off dirt and residue and store the wrench in a toolbox or on a rack to prevent corrosion and maintain readiness.

Usage recommendations

Use only the appropriately sized end to avoid rounding fastener edges, avoid excessive impact loads as the tool is intended for manual use, and inspect the wrench regularly for wear or deformation before applying significant torque.
