Manufactured from Grade 8 steel with a zinc-plated finish, it provides corrosion resistance and load distribution across the clamping surface. The washer measures 3\/8 inches inner diameter, 7\/8 inches outer diameter, and 5\/64 inches thick. These dimensions follow USS (United States Standard) sizing, which specifies a larger outer diameter than SAE equivalents — making them well suited for applications where wider bearing surface area is needed to prevent fastener pull-through.\u003c\/p\u003e\n\u003cp\u003eThis washer is used across a broad range of mechanical, structural, and trade assembly applications. Electricians, plumbers, HVAC technicians, and general contractors commonly stock USS flat washers for equipment mounting, panel attachment, pipe hanger installations, and mechanical assembly work. The zinc plating makes the part appropriate for indoor and light-duty outdoor environments where mild corrosion resistance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUSS flat washer profile — larger OD than SAE for increased bearing surface\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction for high-strength fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in indoor and light outdoor environments\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch ID fits standard 5\/16-inch screw shanks with proper clearance\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch OD distributes clamp load across a wider surface area\u003c\/li\u003e\n  \u003cli\u003eInch measurement system — compatible with standard SAE fastener hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16-inch screws and bolts following USS flat washer dimensional standards.
