It carries a 3\/8-inch nominal bolt size, a 1-inch outside diameter, and a 7\/16-inch inside diameter. The zinc finish provides corrosion resistance suitable for general indoor and light-duty outdoor applications. Plumbers, electricians, HVAC technicians, and general contractors reach for this washer wherever a USS-pattern flat washer is called out on threaded assemblies.\u003c\/p\u003e\n\u003cp\u003eThis washer fits standard 3\/8-inch fastener applications across residential and light commercial construction and mechanical work. Typical uses include pipe hanger assemblies, equipment mounting, electrical panel and conduit support brackets, and structural fastening where a larger bearing surface is needed to prevent pull-through or surface damage. Its zinc coating makes it a practical choice for interior mechanical rooms and similar environments where mild corrosion exposure is a factor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUSS standard flat washer profile provides a larger outside diameter relative to bolt size for improved load distribution\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch nominal bolt size with 7\/16-inch inside diameter for a proper slip fit on standard 3\/8-inch threaded fasteners\u003c\/li\u003e\n  \u003cli\u003e1-inch outside diameter spreads clamping force across a wider surface area\u003c\/li\u003e\n  \u003cli\u003eZinc finish offers corrosion resistance for general-purpose indoor and protected outdoor use\u003c\/li\u003e\n  \u003cli\u003eWidely compatible with pipe hanger hardware, equipment mounting, and conduit support applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a USS-pattern flat washer for use with 3\/8-inch threaded fasteners in standard mechanical, plumbing, HVAC, and electrical installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall between the fastener head or nut and the mating surface to distribute load and reduce surface damage.
