It features a 5\/8-11 UNC thread size and a 5-inch length under head, manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 steel delivers the tensile strength required for demanding structural and mechanical assemblies. The zinc yellow dichromate coating provides corrosion resistance in environments where bare steel would be inadequate. This fastener conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for applications where specification compliance is required. Installation is performed by maintenance technicians, millwrights, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy-duty bolted connections in industrial machinery, structural steel assemblies, agricultural equipment, and general mechanical fabrication. The partial threading allows for a clean shank bearing surface in clearance holes, which is important in shear-loaded joints. It is sized for use with a 5\/8-11 UNC nut or tapped hole. Typical applications include equipment mounting, frame assembly, and structural fastening where Grade 8 strength is specified by design requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread form per standard coarse-thread series\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head with partial threading for shank bearing surface\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eHex head drive for use with standard open-end, box, or socket wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 5\/8-11 UNC partially threaded hex head cap screw meeting ASME B18.2.1 and Grade 8 material specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed with appropriate hand or power tools rated for 5\/8-inch fasteners.
