Value Collection 39761 Uss Flat Washer 1-1/4 in Steel

Product Description

The VALUE COLLECTION 39761 is a USS flat washer designed for use with 1-1/4 inch screws and bolts. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this washer provides a broad bearing surface that distributes clamp load and reduces fastener pull-through on structural and general mechanical assemblies. The 1-3/8 inch inside diameter fits over a 1-1/4 inch fastener shank with standard USS clearance. At 11/64 inch thick and 3 inches in outside diameter, it meets USS dimensional standards for heavy-duty fastening applications. Installation is performed by plumbers, pipefitters, electricians, HVAC mechanics, and general tradespeople working on equipment assemblies, structural connections, and utility installations.

This washer is suited for residential and commercial applications where a large outer diameter is needed to spread load across soft or oversized clearance holes. Typical uses include equipment mounting, pipe hanger assemblies, ductwork supports, electrical panel anchoring, and structural bolted connections. The zinc yellow dichromate coating provides moderate corrosion resistance for interior and semi-exposed installations. Sold individually, with a minimum order quantity of 20 pieces.
