Value Collection SSWASHER5376 5/16 in Flat Washer 18-8 Ss

Product Description

The VALUE COLLECTION SSWASHER5376 is a standard flat washer for 5/16 inch screw applications, manufactured from 18-8 stainless steel for reliable corrosion resistance. With an inside diameter of 11/32 inches, an outside diameter of 11/16 inches, and a thickness of 0.065 inches, this washer distributes load evenly across fastened surfaces and helps prevent pull-through in a wide range of assemblies. Conforming to ASME B18.22.1 1965, it meets recognized dimensional standards for inch-series flat washers. Plumbers, pipefitters, HVAC technicians, and electricians regularly use stainless flat washers wherever moisture exposure or chemical contact rules out carbon steel hardware.

This washer is suited for residential and light commercial applications where corrosion resistance is a priority. Typical uses include equipment mounting, pipe hanger assemblies, duct support hardware, panel fastening, and general mechanical assembly with 5/16 inch fasteners. The 18-8 stainless steel alloy is appropriate for both indoor and outdoor installations exposed to humidity, mild chemicals, or occasional water contact.
