Value Collection USFW0100100OZ Uss Flat Washer No. 10

Product Description

The VALUE COLLECTION USFW0100100OZ is a USS flat washer designed for use with No. 10 screws in general industrial, mechanical, and trade assembly applications. Manufactured from steel with a zinc-plated finish, it provides a broad bearing surface that distributes load and reduces the risk of fastener pull-through on softer materials. With an inside diameter of 0.25 inches, an outside diameter of 0.5625 inches, and a thickness of approximately 0.047 inches (3/64 inches), this washer conforms to USS (United States Standard) dimensional standards. It is sold individually but must be ordered in multiples of 100 units per order.

This washer suits a wide range of fastening tasks encountered in HVAC equipment assembly, electrical panel work, plumbing fixture mounting, and general mechanical service. The USS specification calls for a larger outside diameter relative to the screw size compared to SAE washers, making it well suited for applications where load spreading is a priority. The zinc-plated steel construction offers moderate corrosion resistance for indoor and sheltered outdoor environments. Technicians working on sheet metal enclosures, equipment brackets, and structural connections will find this washer a reliable standard-stock item.

Compatibility

Designed as a standard USS flat washer for use with No. 10 inch-series screws and bolts in general mechanical, HVAC, electrical, and plumbing assembly work.

Installation Notes

Installation requires no special tools beyond standard hand or power drivers appropriate to the mating fastener. Place the washer between the fastener head or nut and the mating surface to distribute clamping load. For applications subject to moisture or outdoor exposure, consider whether the zinc-plated finish provides adequate corrosion protection for the service environment. Always select the correct screw size and washer series (USS vs. SAE) before assembly to ensure proper fit and load rating.
