Ring wrench Proline 36020 — hand tool, 1 pcs pack

Proline 36020 ring wrench is a single-piece hand tool designed for fastening and loosening nuts and bolts with a closed ring head. Forged and chromium-plated with a satin finish, the wrench meets dimension-related requirements of the German DIN 838 standard and offers increased torque capacity compared with common standards. Supplied as a one-piece pack, it is intended for workshop, garage and household use where a durable ring-type wrench is required for reliable torque application.

Advantages

The forged construction provides high strength and resistance to deformation under load. A chromium-plated satin finish protects against corrosion while reducing glare during work. Meeting DIN 838 dimension requirements ensures compatibility with fasteners manufactured to that standard. The design allows the tool to deliver up to 60% higher maximum torque compared with tools made to DIN 899 or common US ANSI dimensions, enabling more secure tightening and easier loosening of stubborn fasteners.

Suitable for

• General mechanic and maintenance work in workshops and garages
• Household repairs where ring wrenches are required for enclosed fasteners
• Automotive tightening and loosening of nuts and bolts in confined spaces
• Industrial or equipment servicing that requires standardized wrench dimensions

Key specifications

• Construction: forged steel
• Surface finish: chromium-plated, satin
• Standard compliance: dimension-related requirements of DIN 838
• Torque capability: maximum torque up to 60% higher than comparable DIN 899 and ANSI tools
• Packaging: single-piece pack

How to use

Select the ring wrench size that fits the nut or bolt head precisely to avoid rounding. Place the closed ring over the fastener head so the wrench fully engages the flats, then apply steady force in the required direction to tighten or loosen. Use controlled, steady pressure rather than sudden shocks; when extra leverage is needed, ensure you use proper technique and do not extend the handle with improvised levers. After use, clean the tool, remove debris from the ring head, and store in a dry place to preserve the chromium plating.

Usage recommendations

For safe and effective operation, match the wrench size to the fastener, avoid excessive impact loads, and inspect the tool regularly for wear or damage. Maintain the satin chromium finish by wiping down after use and storing in a dry toolbox to minimise corrosion and preserve fit with standardized fasteners.
