Value Collection FWSIS1120-025BX Sae Flat Washer Steel

Product Description

The VALUE COLLECTION FWSIS1120-025BX is a steel SAE flat washer with a zinc-plated finish, sized for 1-1/8 inch screws. It features a 1-3/16 inch inside diameter, 2-1/4 inch outside diameter, and a 9/64 inch thickness. The zinc plating provides corrosion resistance for general-purpose fastening applications. This washer distributes load across the bearing surface of a bolted joint, reducing the risk of damage to the mating material. Plumbers, HVAC technicians, electricians, and general contractors use SAE flat washers in a wide range of structural and mechanical assemblies.

This washer suits residential and light commercial fastening applications where SAE-standard dimensions are specified. It is appropriate for use with 1-1/8 inch fasteners in steel, wood, and similar substrates. The zinc-plated steel construction makes it suitable for indoor and dry-to-moderate-humidity environments. Typical use cases include pipe hanger assemblies, equipment mounting, ductwork supports, and general mechanical connections where load distribution is required.

Compatibility

Designed as a standard SAE flat washer for use with 1-1/8 inch screws and bolts in general mechanical, structural, and trade fastening applications.

Installation Notes

Install using standard hand tools appropriate for the fastener type. Ensure the washer seats flat against the mating surface before torquing the fastener. For structural or code-governed assemblies, consult applicable building or mechanical codes for washer and fastener requirements. This washer is intended for dry to moderate indoor environments; use stainless or hot-dip galvanized hardware where prolonged moisture or outdoor exposure is expected.
