Ratcheting Wrench Proxxon 18 mm model 23140, compact hand tool for tightening and loosening nuts

Proxxon ratcheting wrench model 23140 is an 18 mm compact hand tool designed for tightening and loosening nuts and bolts in confined spaces. The integrated low-profile ratchet mechanism enables continuous motion without repositioning the tool, reducing time on repetitive tasks. Built for workshop and field use, this wrench combines a slim head profile with a comfortable handle to reach fasteners in tight assemblies commonly found in automotive maintenance, plumbing and mechanical repairs.

Advantages

The compact ratchet head allows access to fasteners where a conventional wrench cannot fit. The 18 mm jaw size fits standard nuts and bolts of that dimension, while the ratcheting function provides quicker operation compared with fixed wrenches. The tool’s construction offers reliable torque transfer and a slim profile that improves maneuverability in restricted areas. Its simple mechanism requires minimal maintenance and is suitable for repeated professional or DIY use.

Suitable for

• Automotive maintenance and repair
• Assembly and production tasks with confined access
• Plumbing installations and pipe fittings
• General mechanical repairs and household maintenance

Key specifications

How to use

Select the 18 mm Proxxon ratcheting wrench and engage the jaw over the nut or bolt head. Apply steady pressure and move the handle in the ratchet direction to tighten or loosen the fastener; the mechanism permits repeated motion without removing and repositioning the wrench. To change direction, use the ratchet reversal control (if present) or flip the wrench as appropriate. After use, wipe clean and store the wrench in a dry place to prevent corrosion.

Usage recommendations

Use the wrench only on fasteners that match the 18 mm size to avoid rounding edges. Do not apply impact force or use a cheater bar; the tool is intended for manual operation. For work in oily or dirty environments, clean contact surfaces regularly and inspect the ratchet mechanism for wear. When higher torque is required, consider using a torque-specified tool to avoid over-tightening.
