Value Collection FWUIS3000-010BX Uss Flat Washer 3 in

Product Description

The VALUE COLLECTION FWUIS3000-010BX is a USS flat washer designed for use with 3-inch screws and fasteners. Manufactured from steel with a zinc-plated finish, it provides corrosion resistance in general-purpose mechanical and structural applications. The washer meets ASME B18.21.1 standards, confirming dimensional accuracy and material compliance. With an inside diameter of 3.125 inches, an outside diameter of 5.5 inches, and a thickness of 0.249 inches, it distributes load across a wide bearing surface. Plumbers, electricians, pipefitters, and general contractors install these washers when fastening large-diameter bolts and threaded rod assemblies.

This washer is suited for residential and commercial mechanical, structural, and utility installations where a large-diameter USS-pattern flat washer is required. It is commonly used with heavy hex bolts, carriage bolts, and anchor rods in piping hangers, equipment mounting, and structural connections. The USS pattern provides a broader outer diameter relative to screw size compared to SAE-pattern washers, making it appropriate for use with oversized clearance holes and softer substrate materials.

Key Features

Compatibility

Designed as a USS-pattern flat washer for use with 3-inch nominal screw and bolt sizes in inch-measurement fastener assemblies conforming to ASME B18.21.1.

Installation Notes

Installation is performed by licensed tradespeople or qualified mechanical contractors working with large-diameter fastener assemblies. Always ensure the mating bolt, nut, and substrate are rated for the intended load before torquing the assembly. Inspect the washer for burrs or plating defects before installation. Follow applicable structural or mechanical codes for fastener torque requirements based on bolt grade and application.
