Wrench Proxxon 10x13 mm Slim-Line PR23838 – flat open-end wrench, metric sizes 10 and 13 mm

Proxxon Slim-Line flat open-end wrench PR23838 is a compact, low-profile hand tool designed for working with metric fasteners sized 10 mm and 13 mm. The slim, flat body provides improved access in confined spaces and between closely positioned components. Manufactured for general workshop and automotive use, the wrench combines a precise fit for hex heads with a narrow profile to reduce interference when turning nuts and bolts in restricted areas.

Advantages

The slim-profile construction allows access where standard open-end wrenches cannot reach, while still delivering the leverage needed for tightening and loosening 10 mm and 13 mm fasteners. Flat, parallel jaws ensure a secure contact with nut and bolt heads to minimize rounding. Durable material and accurate machining provide consistent performance and long service life in workshop and maintenance environments.

Suitable for

• Tight-space mechanical work where clearance is limited
• Automotive maintenance and minor repairs on cars and motorcycles
• General workshop tasks involving 10 mm and 13 mm hex fasteners
• Assembly and disassembly of machinery with closely spaced components

Key specifications

• Type: Flat open-end wrench (slim-line profile)
• SIZES: Metric 10 mm and 13 mm jaw openings
• Profile: Slim, low-clearance design for tight access
• Material: Hardened and machined steel for wear resistance
• Finish: Corrosion-resistant surface treatment
• Length: Short compact length for maneuverability in confined spaces

How to use

Select the jaw size that matches the nut or bolt head (10 mm or 13 mm) and position the wrench so the flat jaws fully engage the flats of the fastener. Apply steady, controlled force in the required direction to tighten or loosen the fastener, taking care to maintain full contact to avoid slipping. The slim profile is intended for use in confined or recessed areas where a standard open-end wrench would not fit; combine with extension techniques or additional tools only if needed and safe.

Usage recommendations

Inspect the wrench before use for wear or deformation of the jaws. Use the correct size to avoid damage to fasteners and tool. Avoid applying excessive torque beyond the capacity of an open-end wrench; when higher torque is required, consider using a socket or boxed wrench designed for greater mechanical advantage. Store in a dry place after cleaning to maintain the corrosion-resistant finish.
