Sized at 1\/2-13 thread with an overall length of 2.5 inches, it is driven with a 1\/4-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. Manufactured from Grade 8 alloy steel, this screw delivers high tensile and torsional strength suitable for demanding industrial and trade applications. It is a headless fastener, meaning the set screw sits flush or below the surface of the workpiece, preventing interference with rotating or moving components. Machinists, millwrights, and maintenance technicians commonly specify this type of fastener for collar, gear, and pulley retention on shafts.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in industrial machinery, conveyor systems, motor shaft assemblies, and general mechanical fabrication wherever a headless, flush-mount fastening solution is required. The cup point configuration bites into the mating shaft surface under torque load, providing strong rotational and axial holding power without requiring a separate locking element. It is suited for both original equipment manufacturing and field repair work in commercial and industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface for reliable holding under load\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread for broad tool and hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive size for standard hex key installation\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows flush or below-surface seating\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC cup point set screw for use in any application requiring an ASME\/ANSI B18.3 compliant headless socket set screw in Grade 8 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/4-inch hex key. De-energize and lock out any equipment before servicing shaft-mounted assemblies. Apply appropriate thread-locking compound if vibration loosening is a concern in the application.
