Value Collection FWUIS018-100BX Uss Flat Washer Size 10

Product Description

The VALUE COLLECTION FWUIS018-100BX is a USS flat washer designed for use with size 10 screws. It features a 1/4-inch inside diameter, a 9/16-inch outside diameter, and a 3/64-inch thickness. Made from steel with a plain finish, this washer distributes load across fastened surfaces, reduces stress on the mating material, and helps prevent pull-through. It is a standard inch-measurement washer conforming to USS dimensional standards. This part ships in a minimum order quantity of 100 pieces per order, making it suited for both bench-stock replenishment and project-volume purchasing by trade professionals and maintenance crews.

USS flat washers like the FWUIS018-100BX are used across a wide range of mechanical and structural assembly applications. Common installations include HVAC equipment mounting, pipe hanger assemblies, electrical panel and enclosure hardware, and general trade fastening tasks where a broad bearing surface is needed under a screw or bolt head. The plain steel finish is appropriate for dry indoor environments and protected assemblies where corrosion resistance is not a primary requirement.

Installation Notes

USS flat washers are installed by any trade professional performing mechanical assembly or equipment mounting. Always power down or de-energize equipment before servicing fastened assemblies in electrical or HVAC systems. Ensure the washer is seated flat against the mating surface with no cocking or misalignment before torquing the fastener. Follow applicable codes such as NEC or IFGC for fastener and hardware specifications in regulated installations.
