Williams Comfort Products 471 Adjustable Hook Spanner

Product Description

The WILLIAMS COMFORT PRODUCTS 471 is an adjustable hook spanner wrench designed to grip and turn slotted, notched, or face-spanner style fasteners across a range of sizes from 3/4 inches up to 2 inches. The adjustable design allows a single tool to handle multiple fastener diameters, reducing the number of dedicated spanners a technician needs to carry. It is used in mechanical and plumbing service work where standard open-end or socket wrenches cannot engage recessed or face-mounted retaining rings, bearing lockrings, and similar threaded collars. Weighing 0.26 pounds, it is a lightweight hand tool suited for bench work and field service alike.

The 471 hook spanner is appropriate for use in residential and commercial service environments where technicians encounter face-spanner fasteners on pump housings, valve assemblies, bearing retaining nuts, and similar components. Plumbers, HVAC technicians, and mechanical service professionals will find it useful when disassembling or reassembling equipment with slotted retaining rings that require a spanner-style engagement. The adjustable range of 3/4 inches to 2 inches covers the most common fastener sizes found in light mechanical and plumbing equipment.

Compatibility

Installation Notes

This tool is used by plumbers, HVAC technicians, and mechanical service professionals during equipment disassembly and reassembly. Always relieve system pressure and shut off fluid or refrigerant supply before disassembling any valve, pump, or bearing assembly. Ensure the spanner hook is fully seated in the fastener slot before applying torque to avoid slipping and damaging the fastener face.
