With a 7\/16-20 UNF thread size and a 2-1\/2 inch length under head, this fastener is partially threaded per ASME B18.2.1 and SAE J429 standards. Grade 8 steel construction provides superior tensile strength compared to lower-grade fasteners, making it suitable for demanding mechanical and structural assemblies. Machinists, millwrights, HVAC equipment installers, and other trade professionals rely on this grade when torque loads and joint integrity are critical.\u003c\/p\u003e\u003cp\u003eThis hex head cap screw fits applications requiring a fine-thread UNF fastener in the 7\/16 inch diameter class. Partial threading is appropriate for applications where the unthreaded shank must bear shear loads or where precise clamp length control is needed. Common use cases include equipment mounting, machinery assembly, and structural bracketing where Grade 8 rated hardware is specified by the engineer or equipment OEM.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003e7\/16-20 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank suitable for shear-load-bearing joints\u003c\/li\u003e\n\u003cli\u003e2-1\/2 inch length under head for deeper grip requirements\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.2.1 and SAE J429 standards\u003c\/li\u003e\n\u003cli\u003eInch measurement system for standard US fastener compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in applications calling for a 7\/16-20 UNF Grade 8 hex head cap screw per ASME B18.2.1 and SAE J429 specifications.
