Sized at 1-1\/4-7 UNC thread with a 6-inch length under head, this fastener is manufactured from Grade 2 steel and finished with a zinc plating for basic corrosion resistance. It meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards. The hex drive head accepts standard hex wrenches and impact sockets. At 2.58 pounds per unit, this is a substantial fastener suited for structural connections, equipment assembly, and heavy-duty framing work where Grade 2 steel meets load requirements.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in residential and commercial construction, industrial equipment assembly, agricultural machinery, and general fabrication. The partial threading allows for clamping force to be concentrated through the unthreaded shank, making it well suited for bolted joints where the shank passes through clearance holes. Machinists, millwrights, ironworkers, and maintenance technicians commonly install this class of fastener in high-load structural connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head accommodates thick stock and multi-layer assemblies\u003c\/li\u003e\n  \u003cli\u003ePartial threading keeps the shank smooth through clearance holes, concentrating clamping load\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc plating provides baseline corrosion protection for indoor and moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for head dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1-1\/4-7 UNC inch-series nuts and tapped holes conforming to ASME and SAE specifications for Grade 2 steel hex head cap screws.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a properly sized hex wrench or impact socket rated for the fastener size.
