Open-end wrench Proxxon PR23852 21 x 23 mm

Proxxon PR23852 21 x 23 mm open-end wrench is a double-ended hand tool engineered for turning nuts and bolts in the 21 mm and 23 mm metric sizes. The fixed flat-jaw profile provides firm contact with fastener flats, allowing torque transfer for loosening and tightening tasks. Constructed for manual mechanic and maintenance work, this open-end wrench is designed to be used in workshops, garages and industrial environments where durability and accurate fit are required.

Advantages

The open-end design gives quick engagement on two adjacent metric sizes without the need to change tools. Each jaw is precision-formed to reduce slippage and rounding of fasteners when used correctly. Made by Proxxon, the tool combines a compact, slim profile with sufficient strength for routine automotive repair and machinery maintenance. Its double-ended layout saves space in a tool kit and provides a reliable option for working in accessible areas where socket sets may be impractical.

Suitable for

• Automotive repair and brake/engine component maintenance
• General machinery and equipment servicing
• Workshop tasks requiring quick change between 21 mm and 23 mm fasteners
• Field service and on-site mechanical adjustments

Key specifications

• Type: open-end (flat) wrench, double-ended
• Sizes: 21 mm and 23 mm
• Material: forged chrome vanadium steel (typical for this tool class)
• Finish: polished or satin surface for corrosion resistance and ease of cleaning
• Profile: slim head for access in tighter spaces

How to use

Select the jaw size that matches the flats of the nut or bolt and seat the wrench fully on the fastener before applying torque. Apply steady, even force in the required direction; avoid sudden impacts or excessive leverage that can deform the fastener or tool. For best results, ensure the wrench is perpendicular to the fastener axis and re-seat if slippage occurs. When working in confined areas, use the slim profile to reach fasteners where bulkier tools do not fit.

Usage recommendations

Regularly inspect the jaws for wear and clean the wrench after use to maintain fit and prevent corrosion. Use this open-end wrench for manual turning only; do not apply cheater bars or use with impact devices. Store in a tool roll or toolbox to protect the jaws and keep both sizes readily available during maintenance tasks.
