It features a 5\/16-18 UNC thread with an overall length of 5\/8 inches and is manufactured from Grade 8 alloy steel, providing high tensile strength and resistance to loosening under load. The cup point tip bites into the mating surface to resist rotation and axial movement. A 5\/32-inch hex drive accepts a standard hex key for installation and removal. This fastener meets ASME\/ANSI B18.3 and ASTM F912 dimensional and performance standards. Machinists, maintenance technicians, and assembly professionals use this type of fastener across a broad range of industrial and mechanical applications.\u003c\/p\u003e\n\u003cp\u003eCup point set screws are used extensively in shaft-to-hub connections, collars, pulleys, gears, and similar assemblies where a flush or recessed fastener is required. The 5\/16-18 thread size and 5\/8-inch length make this screw appropriate for moderate-duty clamping applications in light industrial equipment, HVAC drive components, pump assemblies, and general mechanical fabrication. This screw is sold individually but must be ordered in multiples of 100.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eCup point tip bites into mating surface to resist rotation and axial displacement\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex drive compatible with standard hex keys and L-wrenches\u003c\/li\u003e\n  \u003cli\u003eUNC 5\/16-18 thread for broad compatibility with inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 standards for dimensional accuracy and mechanical performance\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or recessed, eliminating protrusion hazards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series set screw for use in any 5\/16-18 UNC tapped hole requiring a cup point, headless configuration per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/32-inch hex key or L-wrench. Ensure the receiving hole is cleanly tapped to 5\/16-18 UNC before driving the screw. Power down and de-energize any rotating equipment before accessing shaft collars or drive components.
