Manufactured from Grade 316 stainless steel, it provides superior resistance to chlorides, salt spray, and chemical exposure compared to standard 304 stainless. The washer measures 9\/16 inches inside diameter, 1-3\/8 inches outside diameter, and 0.109 inches thick. These dimensions follow USS flat washer standards, which specify a larger outer diameter relative to the screw size to distribute clamping load across a broader surface area. Plumbers, marine service technicians, and industrial maintenance professionals commonly specify Grade 316 hardware in wet or outdoor environments.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for residential and commercial plumbing assemblies, marine hardware installations, food-processing equipment, and any bolted joint exposed to moisture, salt, or mild chemical agents. The USS geometry makes it appropriate where extra load-bearing surface is needed under a bolt head or nut. It installs with standard hand tools alongside 1\/2-inch bolts or threaded rod in structural and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for high corrosion resistance in chloride and marine environments\u003c\/li\u003e\n  \u003cli\u003eUSS flat washer pattern provides wider outer diameter for improved load distribution\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch inside diameter fits standard 1\/2-inch fasteners with appropriate clearance\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-inch outside diameter and 0.109-inch thickness meet USS dimensional standards\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; compatible with standard SAE\/USS hardware\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 1\/2-inch bolts, screws, and threaded rod in standard inch-series fastener assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlumbers, pipefitters, and general mechanical tradespeople install flat washers as part of bolted joint assemblies. Always ensure the inside diameter clears the fastener shank without excessive play before assembly. Inspect mating surfaces for burrs or debris that could compromise seating.
