It meets ASTM F436 specifications, making it appropriate for structural and heavy-duty fastening applications where consistent load distribution and corrosion resistance are required. The washer measures 0.5880 inches inside diameter, 1.1800 inches outside diameter, and 0.1340 inches thick. Hardness is rated Rockwell C38-42, confirming a through-hardened construction suited to high-load clamp conditions. These are sold in packs of 25.\u003c\/p\u003e\n\u003cp\u003eThis washer is used wherever a 9\/16 inch bolt or cap screw requires a bearing surface that distributes clamp load across a wider area. Typical applications include structural steel connections, equipment mounting, and general mechanical assemblies in construction, industrial, and trade service environments. The SAE flat washer profile and ASTM F436 compliance make it a standard choice for contractors and maintenance professionals working with 9\/16 inch fastener systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM F436 compliant  -  meets structural fastener washer standards\u003c\/li\u003e\n  \u003cli\u003eRockwell C38-42 hardness  -  through-hardened for high-load applications\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard finish  -  protective coating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eSAE flat washer profile  -  wide bearing surface for load distribution\u003c\/li\u003e\n  \u003cli\u003ePrecise dimensions: 0.5880 inches ID, 1.1800 inches OD, 0.1340 inches thick\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 25 for job-site and service use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 9\/16 inch screws and bolts conforming to SAE flat washer dimensional standards.
