Hook Spanner AWTools BLACK LINE with Pivot Pin, 120–180 mm

AWTools Hook Spanner from the BLACK LINE series with a pivot pin is an adjustable hand tool for engaging and turning round nuts, collars and rings with recessed or external surfaces. The spanner adjusts to fit diameters between 120 and 180 mm and is intended for maintenance, assembly and repair work where a reliable grip and controlled torque on circular fasteners are required. Its pivot pin provides additional stability when the working diameter changes within the specified range.

Advantages

The tool offers a wide adjustment range that covers diameters from 120 to 180 mm, reducing the need for multiple fixed-size wrenches. The pivot pin improves alignment and prevents slippage during turning of large or recessed rings. Sturdy construction and an ergonomically shaped handle provide consistent leverage for controlled torque. The design is compact for storage while remaining robust enough for repeated professional use.

Suitable for

• Maintenance and repair of mechanical equipment with circular fasteners
• Assembly and disassembly of collars, retaining rings and large threaded rings
• Plumbing tasks involving circular nuts and fittings
• Industrial equipment servicing where adjustable gripping tools are needed

How to use

Select the approximate diameter within the 120–180 mm range and position the hook over the nut, collar or ring edge. Engage the pivot pin if required to stabilize the hook against the workpiece. Apply steady, controlled force to turn the fastener in the required direction, keeping the spanner aligned to avoid slipping. Release grip and readjust the hook or pivot pin as needed for successive turns until the component is loosened or tightened to the desired position.

Usage recommendations

Inspect the working surface for burrs or damage before use and ensure the hook seats fully to avoid slipping. Use appropriate personal protective equipment and moderate force to prevent overstressing the tool or fastener. For corroded or tightly seized rings, consider using penetrating lubricant and apply torque gradually while monitoring alignment.
