It measures 1\/2-13 x 9 inches, with the 9-inch dimension measured under the head, and features a Unified National Coarse (UNC) thread form. Manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance, this fastener meets ASME B18.2.1 and SAE J429 standards. It is suited for structural assemblies, equipment mounting, and other high-load fastening work where a standardized hex drive and partial thread engagement are required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a wide range of mechanical and industrial installations, including HVAC equipment mounting, pump and motor assembly, structural steel connections, and general fabrication work. The partially threaded shank provides a smooth bearing surface in the grip zone, making it appropriate for clamping joints where the threads should not engage the full length of the hole or mating material. It is appropriate for both shop and field installation by mechanics, millwrights, and trade technicians working in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements for medium-strength fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion protection in dry and mildly humid environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank maintains a full-diameter grip zone along the unthreaded length\u003c\/li\u003e\n  \u003cli\u003eUNC thread form (1\/2-13) is widely compatible with standard nuts and tapped holes in inch-measurement hardware\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003e9-inch under-head length suits deep-reach or through-bolting applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC hex nuts, flat washers, and tapped holes conforming to inch-series thread standards.
