Spanner wrench Proline 36140, 200 mm length, single piece

Proline 36140 spanner wrench is a hand tool with a 200 mm length designed for tightening and loosening nuts and fittings in general mechanical and maintenance tasks. Supplied as a single piece, this spanner wrench features a forged chromium-plated construction and a satin finish for durability and corrosion resistance. The ground head and a socket made of 50BV30 steel provide accurate contact with fasteners while a head range of motion of approximately 220° allows access in confined or awkward spaces.

Advantages

The forged steel body and chromium plating increase strength and protect against wear and rust, while the satin finish reduces glare and fingerprints. A precisely ground head ensures stable engagement with nuts and fittings to minimize rounding. The compact 200 mm length balances reach and control, offering leverage for torque application without sacrificing maneuverability in tight areas. The single-piece design eliminates joints that could weaken under load.

Suitable for

• General mechanical maintenance and assembly
• Plumbing work on nuts and fittings in restricted spaces
• Workshop repairs and equipment service
• Automotive underbody and engine-bay tasks requiring controlled torque

Key specifications

• Overall length: 200 mm
• Construction: forged steel
• Finish: chromium-plated with satin surface
• Head: ground for precise contact
• Socket material: 50BV30 steel
• Head range of motion: approximately 220° ±5°
• Supply: single piece

How to use

Select the spanner wrench and position the socket over the nut or fitting so the ground head seats fully. Apply steady force to the handle in the required direction to tighten or loosen; use controlled, even pressure to avoid slipping and rounding of fasteners. For work in cramped areas, adjust the head within its range of motion to obtain the best leverage and clearance. Inspect the tool and the fastener after each operation to ensure proper engagement and finish.

Usage recommendations

Use the spanner wrench with appropriate personal protective equipment, avoid excessive impact or hammering on the tool, and store it clean and dry to maintain the chromium plating and satin finish. For high-torque applications, use the tool within its designed leverage limits to prevent deformation.
