Built from alloy steel with a zinc yellow dichromate finish, this washer provides corrosion resistance while meeting the dimensional requirements of structural assemblies. It carries a Rockwell C43-C49 hardness rating, making it suitable for use in joints where load distribution and fastener integrity are critical. The 1\/2 inch screw size, 17\/32 inch inside diameter, and 1-1\/16 inch outside diameter make it a standard fit for structural bolting work performed by ironworkers, millwrights, and general contractors.\u003c\/p\u003e\n\u003cp\u003eThis washer is used in structural steel connections, equipment mounting, and heavy-duty mechanical assemblies where a standard flat washer does not provide sufficient bearing surface. The zinc yellow dichromate finish offers moderate corrosion protection, making it appropriate for interior structural work and sheltered exterior applications. It is sold individually per package with a minimum order quantity of 5 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction with Rockwell C43-C49 hardness for high-strength structural use\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e17\/32 inch inside diameter fits 1\/2 inch fasteners with standard clearance\u003c\/li\u003e\n  \u003cli\u003e1-1\/16 inch outside diameter distributes load across a broad bearing surface\u003c\/li\u003e\n  \u003cli\u003e13\/64 inch thickness (0.2031 inches) meets structural washer dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a structural flat washer for use with 1\/2 inch screw and bolt fasteners in structural steel and heavy-duty mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using standard hand and impact tools appropriate for the fastener type and torque specification required by the joint design.
