Value Collection FWUIS0370-10LBBX Uss Flat Washer

Product Description

The VALUE COLLECTION FWUIS0370-10LBBX is a USS flat washer sized for 3/8 inch screws and fasteners. Stamped from steel with a zinc-plated finish for corrosion resistance, it distributes load across the fastener bearing surface to prevent pull-through and surface damage. The washer measures 0.433 inches inside diameter, 1.03 inches outside diameter, and 0.104 inches thick, conforming to USS (United States Standard) dimensional requirements. Electricians, plumbers, HVAC technicians, and general contractors use USS flat washers in structural connections, equipment mounting, and panel assembly where a larger bearing surface is required.

This washer is suited for residential and commercial fastening applications where 3/8 inch bolts or screws are used. Typical uses include mechanical equipment mounting, strut and bracket assembly, pipe hanger installations, and general trade work requiring a standardized inch-series flat washer. The zinc-plated finish provides moderate corrosion protection appropriate for interior and light-duty service environments.

Key Features

• USS flat washer profile provides a wider bearing surface than SAE equivalents for the same screw size
• 0.433 inches inside diameter fits 3/8 inch fastener shanks
• 1.03 inches outside diameter for broad load distribution
• 0.104 inches thickness maintains consistent clamping geometry
• Zinc-plated steel construction resists surface corrosion in standard service conditions
• Inch-series dimensions conform to USS standards for broad interchangeability

Compatibility

Designed for use with 3/8 inch screws and bolts in standard inch-series fastener assemblies following USS dimensional specifications.

Installation Notes

Install with hand tools appropriate to the fastener type — wrenches, sockets, or screwdrivers depending on the bolt or screw head style. Always de-energize electrical equipment and shut off fluid systems before working in proximity to live circuits or pressurized lines. Do not use zinc-plated hardware in submerged, outdoor-exposed, or chemically aggressive environments where hot-dip galvanized or stainless fasteners are required by code or specification. Consult applicable mechanical and structural codes for fastener torque and spacing requirements.
