Value Collection 93701 Uss Flat Washer 5/16 in 18-8 Ss

Product Description

The VALUE COLLECTION 93701 is a USS-pattern flat washer designed for use with 5/16 inch screws and fasteners. Manufactured from 18-8 stainless steel, it provides corrosion resistance suitable for both indoor and outdoor applications. The washer measures 3/8 inches inside diameter and 7/8 inches outside diameter, with a thickness of 0.083 inches. The USS flat washer series follows broader outer-diameter standards compared to SAE washers, distributing load across a larger bearing surface. Plumbers, HVAC technicians, electricians, and general tradespeople commonly use these washers when assembling equipment, piping supports, and structural connections where corrosion resistance is a priority.

This washer is suited for residential and commercial fastening applications where stainless steel is specified to resist rust and chemical exposure. Typical uses include pipe hanger assemblies, equipment mounting, sheet metal work, and general mechanical assembly across HVAC, plumbing, and electrical trade work. The 18-8 stainless steel grade offers good weldability and formability alongside its corrosion-resistant properties. Sold individually per package with a minimum order quantity of 100 pieces, making it practical for stocking in trade shops and service vans.

Installation Notes

Installation requires no specialized tools beyond standard hand or power wrenches appropriate to the fastener being used. Always verify that the washer material is compatible with the surrounding metals to avoid galvanic corrosion in dissimilar-metal assemblies. Follow applicable code requirements such as NEC, IPC, or IFGC when using fasteners and washers in code-governed installations. Inspect washers for deformation before reuse in structural or pressure-bearing applications.
