Manufactured from Grade 8 steel and finished with a zinc yellow dichromate coating, this fastener meets ASME B18.2.1 dimensional standards. The 1\/2-13 UNC thread and 7-1\/2 inch length under head make it suitable for thick structural connections, machinery mounts, and industrial equipment assemblies. Installation is performed with standard hex or socket tooling. Sold in a package quantity of 10.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial, commercial, and heavy mechanical applications where Grade 8 tensile strength is specified. Typical uses include structural steel fabrication, heavy equipment assembly, and mechanical maintenance work. The partial threading is appropriate for joints where a grip length through unthreaded material is required before thread engagement. Machinists, millwrights, and maintenance technicians commonly install fasteners of this type.\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 ratings\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for a full grip length in bolted joints\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread form for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 10 with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC inch-series hex nuts, flat washers, and lock washers in Grade 8 or compatible hardware assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized hex wrench, socket, or impact driver rated for the fastener grade.
