It features a 1\/2-13 UNC thread size with a 7-1\/2 inch length measured under the head, and partial threading along the shank. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets the dimensional and mechanical requirements of ASME B18.2.1. Its high tensile strength makes it suitable for demanding bolted connections where a standard Grade 5 fastener would be insufficient. The 3\/4-inch hex drive is compatible with standard open-end, box-end, and socket wrenches used in trade and maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is commonly used in structural steel connections, heavy equipment assembly, machinery mounting, and industrial maintenance applications. Partial threading leaves a smooth shank section that provides shear strength and precise clamping in close-tolerance joint designs. It is appropriate for both original equipment assembly and field repair work performed by millwrights, maintenance technicians, pipefitters, and general mechanical contractors.\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\u003e1\/2-13 UNC thread form for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e7-1\/2 inch length under head accommodates thick stack assemblies\u003c\/li\u003e\n  \u003cli\u003ePartial threading provides a smooth shank for shear-loaded joints\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with added lubrication or field-applied coatings\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-13 UNC standard hex nuts, heavy hex nuts, and appropriately tapped structural components per ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down and de-energize any equipment before replacing fasteners in electrical or mechanical enclosures.
