Manufactured from Grade 8 alloy steel, this screw features a 1\/4-20 UNC thread and measures 5\/16 inches in overall length. The 1\/8 inch internal hex drive accepts a standard hex key for installation and removal. It meets ASME\/ANSI B18.3 and ASTM F912 standards, making it appropriate for applications that require dimensional and mechanical compliance. Machinists, millwrights, and maintenance technicians use cup point set screws to lock shafts, collars, pulleys, and gears in place.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for light to medium-duty industrial and mechanical applications. The cup point geometry bites into the mating surface to resist rotation and axial movement, providing reliable holding power in shaft-to-hub connections. It is a fractional inch fastener on a UNC thread, common in general industrial, HVAC equipment, and mechanical drive assemblies. Sold individually with a minimum order quantity of 100 pieces, it is intended for professional use in production, maintenance, and repair environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point geometry bites into mating surfaces for positive holding in shaft and collar assemblies\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC thread with 5\/16 inch overall length for compact, flush-mount fastening\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction provides high tensile and torsional strength\u003c\/li\u003e\n\u003cli\u003e1\/8 inch hex drive compatible with standard hex keys and Allen wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard fractional inch UNC set screw for use in mechanical assemblies, shaft collars, pulleys, gears, and similar hardware requiring a 1\/4-20 threaded cup point fastener.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 1\/8 inch hex key.
