Featuring a cup point tip, this screw bites into mating surfaces to resist rotation and axial movement without the need for a protruding head. The hex socket drive accepts a 0.05-inch hex key for installation in tight or recessed spaces. It meets ASME\/ANSI B18.3 and ASTM F912 standards, making it a reliable choice for precision assemblies where dimensional consistency and material strength are critical. Machinists, millwrights, and maintenance technicians commonly install these fasteners in pulleys, collars, and shaft-mounted components.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for applications in manufacturing, industrial maintenance, and mechanical repair environments where a flush or below-surface fastener is required. The 4-40 UNC thread and 3\/4-inch overall length make it appropriate for use in light-duty precision components and instrument-grade assemblies. Sold individually per package with a minimum order quantity of 100 pieces, this fastener is intended for shops and technicians sourcing in bulk for ongoing production or repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip grips mating surfaces to prevent rotation and axial shift\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eHex socket drive sized at 0.05 inches for use with standard hex keys in confined spaces\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard ensures compatibility with common tapped holes in precision components\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards for dimensional and mechanical consistency\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch overall length suits a range of collar, pulley, and shaft-locking applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC set screw for use in any tapped through-hole or blind hole conforming to the 4-40 thread specification, including collars, shaft hubs, and mechanical assemblies requiring a cup point fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a calibrated hex key matched to the 0.05-inch drive size. Ensure the mating component is de-energized and secured before tightening. Do not over-drive the cup point, as excessive force can damage soft shaft materials or strip the thread.
