Value Collection USFW1000025OZ Uss Flat Washer 1 in Steel

Product Description

The VALUE COLLECTION USFW1000025OZ is a USS-pattern flat washer designed for use with 1-inch screws and bolts. Manufactured from Grade 2 steel with a zinc-plated finish, it provides corrosion resistance suited to general-purpose fastening applications. The washer measures 1.055 inches inside diameter, 2.530 inches outside diameter, and 0.192 inches thick, conforming to USS (United States Standard) dimensional specifications. This package contains 25 washers. Plumbers, electricians, HVAC technicians, and general trade contractors use USS flat washers daily for load distribution under bolt heads and nuts in mechanical assemblies and equipment installations.

USS flat washers are a standard fastening component across residential and light commercial construction, mechanical rooms, equipment pads, pipe hangers, electrical enclosures, and ductwork supports. The wider outside diameter of the USS pattern distributes clamping load over a larger surface area compared to SAE washers, making them appropriate for softer materials and applications requiring greater bearing surface. This 25-piece pack is sized for job-site replenishment or bench stock use by trade professionals.

Installation Notes

USS flat washers are installed by any trade using bolted connections, including HVAC, plumbing, electrical, and general mechanical work. Always de-energize equipment or relieve system pressure before working on bolted assemblies in live systems. Inspect washers for deformation or corrosion before reuse. Follow applicable code requirements for fastener selection, including NEC, IPC, and IFGC references where structural or equipment-mounting connections are involved.
