Set screws are headless fasteners used to lock a component — such as a collar, gear, pulley, or sprocket — onto a shaft by applying direct clamping force. The knurled cup point bites into the mating surface, increasing resistance to rotation and axial movement. Drive is via a 3\/16 inch hex key. This fastener meets ASME\/ANSI B18.3 and ASTM F912 standards and is sold in a package of 25 pieces. Machinists, millwrights, and mechanical contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThese set screws are suited for general industrial and mechanical assembly applications where a flush or recessed fastener is required. Typical use cases include securing shaft-mounted components in motors, conveyor systems, and mechanical drives in both commercial and light industrial settings. The UNC thread form (3\/8-16) provides broad compatibility with standard inch-series tapped holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point bites into shaft surface for improved torque and axial load resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex key drive for recessed installation in tight clearance applications\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard (3\/8-16) for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 25 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC set screw for use in any application with a 3\/8-16 tapped hole requiring a knurled cup point headless fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/16 inch hex key. De-energize or lock out any machinery before installing or adjusting set screws on rotating components. Ensure the mating shaft surface is clean and free of debris to allow proper cup point seating.
