Manufactured from Grade 8 alloy steel, this screw delivers the high tensile strength needed in demanding mechanical assemblies. The 1-72 thread (UNF) and 1\/8-inch overall length make it suited for small-bore, tight-tolerance work. A hex socket drive requires a 0.028-inch hex key for installation. Meets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards. Installed by machinists, maintenance technicians, and mechanical assemblers in industrial and precision equipment environments.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in applications where a shaft, collar, gear, pulley, or similar component must be secured within a bore without a protruding head. The cup point digs into the mating surface to resist rotation and axial movement under load. Typical installations include motor shafts, shaft collars, and set-screw-style couplings in both light industrial and precision instrument contexts. The 1-72 UNF thread pitch is common in miniature and instrument-grade assemblies where fine thread engagement is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into mating surface to resist shaft rotation and axial slippage\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e1-72 UNF thread for fine-pitch, miniature fastening applications\u003c\/li\u003e\n  \u003cli\u003eHex socket drive (0.028-inch hex key) for installation in confined spaces\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 standards for dimensional and material compliance\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below surface for zero protrusion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use set screw for miniature mechanical assemblies requiring a 1-72 UNF thread, 1\/8-inch overall length, and cup point contact geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 0.028-inch hex key; use of an improperly sized key risks rounding the socket drive.
