Value Collection FWUIS300-010BX Uss Flat Washer 3 in

Product Description

The VALUE COLLECTION FWUIS300-010BX is a USS flat washer designed for use with 3-inch screws and fasteners. Manufactured from steel with a plain finish, this washer distributes load across the bearing surface to reduce fastener pull-through and protect the mating material. The 3-1/8-inch inside diameter, 5-1/2-inch outside diameter, and 9/32-inch thickness conform to USS flat washer dimensional standards, making it a straightforward replacement or new-installation choice for heavy-duty fastening applications. Tradespeople working in structural, mechanical, and industrial settings will find this washer meets standard fitment requirements for large-diameter fasteners.

This washer is suited for use in commercial and industrial fastening applications where large-diameter bolts and screws require load distribution across a wider surface area. Typical install scenarios include structural steel connections, heavy equipment assembly, pipe flange work, and general mechanical maintenance. The plain steel finish is appropriate for interior and dry-environment applications. This item is sold individually, with a minimum order quantity of 10 pieces.
