Ring wrench Proline 36512 — single-piece hand tool, 1 pc

Proline 36512 is a single-piece ring (box) wrench supplied as one unit. Manufactured by Proline, this hand tool features a closed ring end for reliable engagement with hexagonal and bi-hex fasteners. The wrench is cold-forged with ground heads and a chromium-plated finish for improved durability and corrosion resistance. It is intended for professional and DIY mechanical, automotive and general maintenance tasks where a single, precise ring wrench is required.

Advantages

The cold-forged construction increases strength and fatigue resistance, while ground heads ensure accurate seating on fasteners to reduce rounding. Chromium plating protects the surface from rust and simplifies cleaning after use. As a single-piece tool, this ring wrench offers compactness and ease of handling in confined spaces and provides firm, full-contact engagement with the fastener for secure torque application.

Suitable for

• Tightening and loosening hex nuts and bolts in automotive repair
• Mechanical assembly and disassembly tasks
• General household and workshop maintenance where a closed ring end is preferred

How to use

Select the appropriate size that matches the fastener and place the closed ring end fully over the nut or bolt head. Ensure the wrench seats squarely on the fastener to minimize slippage. Apply steady hand force in the required direction to tighten or loosen; avoid sudden jerks. Because the tool is single-piece and chrome-plated, wipe clean after use and inspect for any damage before storing.

Usage recommendations

Use the Proline 36512 ring wrench with hand force only and avoid impact tools unless the wrench is specifically rated for such use. Store the tool in a dry place to preserve the chromium finish and periodically check the head fit on fasteners to maintain accuracy and safety.
