Measuring 7\/8-9 thread size with a 15-inch length under the head, this fastener is partially threaded and conforms to ASME B18.2.1 dimensional standards. The bright, uncoated finish is standard for Grade 8 fasteners intended for use with plated hardware or in applications where an additional coating is applied on-site. At 2.67 pounds, this is a substantial fastener suited for high-load assemblies requiring reliable clamping force.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is commonly used in structural steel fabrication, heavy equipment assembly, agricultural machinery, and industrial maintenance. The 7\/8-9 UNC thread profile is a widely specified size in North American manufacturing and construction. Partial threading allows for shank engagement in applications where bearing load across an unthreaded shank is required, such as slip-fit joints or high-shear connections. Installers in fabrication shops, millwright trades, and industrial maintenance crews will encounter this fastener in frames, flanges, and structural bolted joints.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength in demanding load-bearing applications\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread profile, a standard North American coarse-thread designation\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides shear resistance in slip-fit and close-tolerance joints\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional accuracy and interchangeability\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with standard Grade 8 nuts and hardened washers\u003c\/li\u003e\n  \u003cli\u003e1-15\/16 inch hex key size for use with standard heavy-hex impact sockets or wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.2.1 Grade 8 hex head cap screw compatible with 7\/8-9 UNC threaded nuts and tapped holes in steel assemblies requiring high-strength fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by millwrights, ironworkers, maintenance mechanics, or other qualified trades using a 1-15\/16 inch socket or open-end wrench. De-energize and lock out any equipment before replacing fasteners in live mechanical assemblies. Grade 8 fasteners should be paired with Grade 8 or equivalent nuts and hardened washers to maintain rated clamp load.
