Sized at 1-3\/4-5 thread with a 6-inch length under the head, this fastener is manufactured from Grade 8 steel with a bright uncoated finish. The partial threading conforms to ASME B18.2.1 standards, making it suitable for load-bearing bolted connections where a defined grip length is required. At 6.2 pounds, this is a substantial fastener intended for demanding service environments. Machinists, millwrights, and maintenance technicians typically install this class of hardware.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in heavy industrial machinery, structural steel connections, and equipment fabrication where UNC thread and Grade 8 strength are specified. The partially threaded shank provides a bearing surface for precision alignment in bolted joints. Applications include manufacturing plant equipment, large-frame assembly, and heavy mechanical systems requiring fasteners rated to Grade 8 tensile standards. It is sold individually, making it practical for repair and replacement work where a single fastener is needed to complete a job.\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 requirements\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank conforms to ASME B18.2.1 for standardized fitment\u003c\/li\u003e\n  \u003cli\u003e1-3\/4-5 UNC thread size for use with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head provides extended grip for thick-section assemblies\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use where additional coatings are not specified\u003c\/li\u003e\n  \u003cli\u003eHex key drive size of 2-5\/8 inches for use with appropriately sized wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with 1-3\/4-5 UNC tapped holes or compatible heavy hex nuts in structural and industrial bolted assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified millwrights, ironworkers, or maintenance technicians familiar with high-strength fastener procedures. Verify that mating threads and bearing surfaces are clean and free of debris before assembly. Use a properly sized wrench matched to the 2-5\/8-inch hex drive to avoid rounding.
