It is partially threaded and supplied with a bright, uncoated finish. Grade 8 steel provides high tensile strength for demanding fastening applications where standard hardware-grade fasteners are not adequate. This fastener conforms to ASME B18.2.1 dimensional standards. It is driven with a 1-5\/16-inch hex key or standard hex socket and is suited for structural, industrial, and mechanical assembly work performed by maintenance technicians, millwrights, and trade professionals.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in heavy-duty bolted joint assemblies across industrial machinery, structural steel connections, agricultural equipment, and general mechanical fabrication. The partial threading allows it to pass through clearance holes and clamp mating components along the unthreaded shank. The 9-inch length under head makes it appropriate for thick-stack applications where shorter fasteners are insufficient. Installation typically involves a matching 7\/8-9 UNC nut and hardened washer appropriate for Grade 8 service.\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 capacity\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for clearance-hole pass-through and tight clamping\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for use with additional coating or plating if required\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard for reliable fitment\u003c\/li\u003e\n  \u003cli\u003e1-5\/16-inch hex drive compatible with standard hex sockets and wrenches\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread for broad availability of matching nuts and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 7\/8-9 UNC threaded nuts and hardened washers in bolted joint assemblies requiring Grade 8 fasteners per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, maintenance technician, or mechanical tradesperson familiar with torqued bolted joint procedures.
