Ring wrench Proline 36018 — single-piece hand tool, closed-end spanner, 1 pc

Proline 36018 is a single-piece ring wrench supplied as one closed-end spanner designed for tightening and loosening hexagonal nuts and bolts. Forged and chromium-plated with a satin finish, this tool meets dimension-related requirements of the German DIN 838 standard and provides increased torque capacity compared with common standards. Its compact, single-piece construction makes it suitable for basic workshop, automotive and household maintenance tasks where a closed-end spanner is needed.

Advantages

The forged steel construction and chromium plating ensure surface durability and corrosion resistance while the satin finish reduces reflections and improves grip perception. Conformance to the DIN 838 dimensional requirements ensures consistent fit on fasteners, and the design achieves a maximum torque that is up to 60% higher than the values typical for the German DIN 899 and US ANSI standards, enabling more reliable operation on tightened connections.

Suitable for

• General mechanical repair and assembly
• Automotive maintenance and servicing
• Household appliance repair and DIY projects
• Tight spaces where a closed-end spanner is required

Key specifications

• Construction: single-piece (forged) closed-end spanner
• Surface treatment: chromium-plated with satin finish
• Standards: dimension-related compliance with German DIN 838
• Torque capacity: maximum torque up to 60% higher than typical DIN 899 and ANSI values
• Packaging: supplied as one piece

How to use

Select the ring wrench size that matches the hexagonal nut or bolt head to ensure a proper fit. Position the closed end fully onto the fastener, verify alignment to avoid rounding, and apply steady force to tighten or loosen. Use controlled, even pressure and avoid sudden jerks; if higher torque is required, confirm the fastener and surrounding components can withstand the load. After use, wipe the tool clean and store it dry to maintain the chromium-plated surface.

Usage recommendations

For safe operation, use the wrench only on correctly fitting fasteners and avoid using extensions or hammers on the handle that could exceed the design torque. Regularly inspect the tool for wear or damage and replace it if deformations or cracks appear. Keep the chromium-plated surface clean and dry to preserve corrosion resistance.
