Spanner wrench Proline 36151, 305 mm, single-piece hand tool

Proline spanner wrench 36151 is a single-piece, forged hand tool with a 305 mm overall length designed for tightening and loosening nuts and fittings. The wrench features a ground head and a socket made from 50BV30 steel, finished with satin chromium plating for corrosion resistance. A head range of motion of approximately 220° allows accurate positioning in many mechanical and maintenance scenarios, making this tool suitable for workshop, service, and home use.

Advantages

The one-piece forged construction ensures structural strength and reduced risk of joint failure under load. Satin chromium plating provides surface protection against rust while maintaining a non-reflective finish for working in varied lighting. The ground head delivers precise contact with fasteners, and the 220° head range of motion gives flexibility when accessing confined or awkward positions.

Suitable for

• General mechanical repairs and maintenance
• Workshop assembly and disassembly tasks
• Service and field maintenance work
• Home DIY projects requiring medium-length spanners

How to use

Select the spanner wrench and position the socket over the nut or fitting so the ground head seats evenly. Apply steady force to the handle in the required direction to tighten or loosen the fastener. Use the head range of motion to approach the fastener from the best angle; avoid sudden impacts or excessive sideways force that could damage the fastener or tool. Keep hands clear of pinch points and maintain a firm grip on the handle during operation.

Usage recommendations

For safe and long-lasting performance, clean the tool after use, remove debris from the ground head, and store it in a dry place. Inspect the tool regularly for wear or deformation, and replace if the head or socket shows significant rounding or damage. Use the appropriate size and avoid using the wrench as a hammer or pry bar.
