Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers elevated tensile strength and corrosion resistance compared to lower-grade hardware. The 5\/16-18 UNC thread pattern and 1-inch length under head make it a standard choice for structural and mechanical assemblies where reliable clamping force is required. It conforms to ASME B18.2.1 and SAE J429 dimensional and mechanical standards. Maintenance technicians, millwrights, and field service professionals working on equipment frames, brackets, and mechanical subassemblies will find this screw appropriate for demanding service conditions.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in industrial equipment assembly, machinery maintenance, HVAC unit framing, electrical enclosure mounting, and general mechanical construction where Grade 8 strength is specified. The fully threaded shank allows engagement along the entire length, making it effective in applications with thinner material stacks or where maximum thread engagement is needed. It is sold individually with a minimum order quantity of 50 pieces, making it practical for shop stock, service van inventory, or job-site replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets SAE J429 mechanical property requirements for high-strength fastener applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and is visually identifiable as a Grade 8 fastener\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement across the full 1-inch length under head\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread size is a widely stocked standard, compatible with common nuts, inserts, and tapped holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fitment across manufacturers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC hex head cap screw for use in any application specifying a Grade 8 fully threaded fastener of this thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench or socket of the appropriate drive size for a 5\/16-18 cap screw.
