Proline Tools 36801 spanner wrench

The Proline Hook Wrench with Claw (articulated) is a hand tool designed for turning collars, round nuts and retaining rings with diameters from 35 to 50 mm. The articulated joint in the head provides improved access in confined or awkwardly angled spaces, allowing the claw to engage securely around the workpiece. This adjustable tool is intended for controlled torque application where a fixed spanner cannot reach or would risk slippage on curved surfaces.

Advantages

The articulated head increases reach and maneuverability in tight spaces while maintaining stable contact between the claw and the nut or collar. Adjustable range covers diameters 35–50 mm, reducing the need for multiple fixed-size tools. The claw design distributes contact pressure to minimize damage to rounded or soft-metal fittings. The tool’s construction provides reliable torque transmission for workshop, plumbing, and industrial maintenance tasks.

Suitable for

• Removing or tightening collar-type nuts and retaining rings with 35–50 mm diameters
• Maintenance and repair work in workshops and industrial settings
• Plumbing tasks where access is limited or fittings are rounded
• Situations requiring controlled torque on non-flat fastening surfaces

Key specifications

• Adjustable working range: 35–50 mm
• Type: hook wrench with claw and articulated joint
• Intended engagement: collars, round nuts and retaining rings
• Hand-operated tool for manual torque application
• Design emphasis: access in confined or angled spaces

How to use

Select the adjustment to match the diameter of the collar or nut, position the claw so it fully engages the workpiece, and orient the articulated head to provide a comfortable hand position and clearance for rotation. Apply steady, controlled force in the required direction; avoid sudden jerks to reduce the risk of slipping. If resistance is high, verify correct engagement and readjust the angle of the head to improve leverage before increasing force.

Usage recommendations

Inspect the claw and articulated joint before use for wear or deformation. Use appropriate personal protective equipment such as gloves and eye protection when working under load. For hardened or corroded fastenings, consider using penetrating lubricant and allow time to penetrate, then recheck engagement to prevent damage to the fitting or tool.
