Ring wrench Proline 36012 — hand tool, 1 pc

Proline 36012 is a single-piece ring wrench engineered for manual tightening and loosening of nuts and bolts. Forged from a single piece of steel and finished with a chromium-plated satin surface, this hand tool is intended for general mechanical and maintenance tasks in workshops, garages and home projects. The design meets the dimensional requirements of the German DIN 838 standard and delivers a higher torque capacity compared with common standards.

Advantages

The one-piece forged construction provides enhanced strength and torsional stability during use, while the chromium-plated satin finish resists corrosion and reduces glare. The ring-end geometry ensures full contact with fasteners to minimise rounding and slipping. Compared with typical equivalents, this model offers a maximum torque that is up to 60% higher than the values specified in the German DIN 899 and US ANSI standards, allowing safer application of greater manual loads within the tool's intended range.

Suitable for

• General mechanical maintenance and repairs
• Automotive and motorcycle workshop tasks
• Home improvement and DIY projects
• Assembly and disassembly of machinery and equipment

Key specifications

• Construction: single-piece forged ring wrench
• Finish: chromium-plated, satin surface
• Standards compliance: dimensionally conforms to German DIN 838
• Torque performance: maximum torque up to 60% higher than common DIN 899 and ANSI values
• Pack quantity: 1 piece per pack

How to use

Select the ring wrench size that correctly matches the fastener. Position the ring end fully over the nut or bolt head to ensure full flank contact, then apply steady manual force in the required direction for tightening or loosening. Avoid sudden impacts or use with power tools not intended for hand tools. After use, wipe clean and store in a dry place to preserve the chromium finish.

Usage recommendations

Use the wrench only on fasteners within the intended size range and avoid levering extensions unless the tool is specifically rated for increased torque. Regularly inspect the ring ends for wear or rounding and replace the tool if any deformation or cracks are visible. For long-term rust protection, keep the tool dry and occasionally apply a light protective oil to the metal surfaces.
