Ring wrench Proline 36016 — 1 pc, hand tool for tightening and loosening nuts and bolts

Proline 36016 ring wrench is a single-piece hand tool designed for engaging and turning nuts and bolts with a closed ring head. Forged construction and chromium-plated satin finish provide corrosion resistance and a smooth surface for workshop and household use. The tool is manufactured to meet the dimensional requirements of the German DIN 838 standard and offers a maximum torque rating that is 60% higher compared with tools made to German DIN 899 and US ANSI standards, making it suitable for applications that require higher torque capacity while remaining compact for manual operation.

Advantages

The forged steel construction increases strength and durability while the chromium-plated satin surface resists rust and reduces glare during work. Meeting DIN 838 dimensional requirements ensures reliable fit on standard fasteners, reducing rounding and slippage. The higher maximum torque capacity compared with DIN 899 and ANSI-rated wrenches provides added safety margin when applying greater turning force. Supplied as a single compact piece, the wrench is easy to store and carry for general maintenance and repair tasks.

Suitable for

• General maintenance and repair of machinery and equipment
• Assembly and disassembly of mechanical components
• Workshop, garage and household tightening and loosening tasks
• Applications requiring a secure closed-head grip to prevent fastener rounding

Key specifications

• Construction: forged steel for improved strength
• Surface finish: chromium-plated satin for corrosion resistance
• Head type: closed ring for full perimeter contact with fasteners
• Standards: manufactured to meet the dimensional requirements of DIN 838
• Torque capability: maximum torque capacity up to 60% higher than tools meeting DIN 899 and ANSI standards
• Supply: single piece

How to use

Select the ring wrench size that fits the nut or bolt snugly and position the closed head fully over the fastener. Apply steady manual force to the handle, pulling or pushing in the intended direction to tighten or loosen. Avoid sudden impacts or using the wrench as a hammer. For stubborn fasteners, apply gradual, controlled force and ensure the tool is correctly seated to minimize slippage and fastener damage. After use, clean off dirt and debris and store in a dry place to maintain the chromium-plated finish.

Usage recommendations

Use the Proline ring wrench within its intended manual torque range; do not retrofit extensions (cheater bars) or use with impact tools. Periodically inspect the ring head and handle for deformation or wear, and replace the tool if any damage is present to ensure safe and reliable operation.
