Value Collection FWUIS1000-10LBBX 1 in Uss Flat Washer

Product Description

The VALUE COLLECTION FWUIS1000-10LBBX is a 1-inch screw size USS flat washer manufactured from Grade 2 steel with a zinc-plated finish. USS flat washers follow the United States Standard series, which specifies larger outer diameters relative to screw size compared to SAE washers, distributing clamp load over a broader surface area. This washer measures 1.055 inches inside diameter, 2.53 inches outside diameter, and 0.192 inches thick. It is a standard fastener component used across mechanical, structural, and general assembly applications by plumbers, electricians, pipefitters, and general contractors.

This washer is suited for residential and commercial applications where a larger bearing surface is needed to spread load, prevent pull-through, or protect softer substrate materials. It is commonly used with bolts and screws in structural connections, equipment mounting, pipe hangers, and general mechanical assemblies. The zinc-plated finish provides basic corrosion resistance appropriate for indoor and sheltered installations.

Key Features

• USS series profile delivers a wider outer diameter for improved load distribution compared to SAE washers
• Grade 2 steel construction provides reliable tensile strength for general-purpose fastening
• Zinc-plated finish offers baseline corrosion resistance for dry and semi-exposed environments
• 1.055-inch inside diameter sized for 1-inch fasteners with standard clearance
• 0.192-inch thickness maintains consistent bearing surface under torque
• Inch measurement system; compatible with standard USS bolt and screw specifications

Compatibility

Designed as an OEM-style replacement or general-use flat washer for 1-inch screw and bolt applications following USS flat washer dimensional standards.

Installation Notes

Installation is performed by any qualified trade professional working with bolted or screwed mechanical connections. Always ensure the fastener and washer are rated for the load requirements of the application before installation. Follow applicable codes such as AISC, NEC, or IPC where structural or trade-specific fastening requirements apply. Do not substitute a USS washer for an SAE washer in applications where a tighter outer diameter tolerance is required.
