Socket wrench Proxxon 23 137, 10 mm, stainless steel, chrome-vanadium

Proxxon 23 137 is a single-piece 10 mm socket wrench made from chrome-vanadium steel with a stainless-steel finish. It is designed for tightening and loosening 10 mm fasteners and combines corrosion resistance with workshop durability. The tool features a high-alloy 72-tooth inner ring gear that allows ratcheting with a working arc of approximately 5° and a 15° offset ring that prevents turning the wrench over, making it suitable for work on flat surfaces. The shaft has been treated with double nickel-plating and a matt chrome finish; socket size is clearly indicated by laser marking.

Advantages

The single-piece construction eliminates joints that can wear or fail, increasing strength and reliability. The 72-tooth inner ring gear ensures fine incremental ratcheting, enabling operation in confined spaces where only small handle movement is possible. Corrosion-resistant surface treatments and chrome-vanadium construction extend service life under workshop and outdoor conditions. Laser-marked sizing improves speed and accuracy when selecting the correct tool.

Suitable for

• Automotive repair and maintenance tasks requiring a 10 mm socket
• Bicycle maintenance and adjustments
• Household repairs and furniture assembly
• Inclusion in professional hand tool sets for workshops and service vans

How to use

Select the Proxxon 23 137 10 mm socket wrench for the corresponding fastener size, seat the socket squarely on the nut or bolt head, and apply steady turning force in the desired direction. The fine-tooth, 72-tooth ratchet mechanism permits effective operation with small handle movements; reverse the lever to change the turning direction without removing the wrench. Use the 15° offset to clear nearby surfaces and maintain comfortable wrist position when working on flat panels.

Usage recommendations

Inspect the socket and fastener for damage before use, keep contact surfaces clean to ensure secure engagement, and avoid applying impact forces or using the wrench with power tools. Store in a dry place to maintain the corrosion-resistant finish and periodically check for wear if used in professional or heavy-duty environments.
