Set screws of this type are used to secure a component — such as a pulley, collar, or gear — onto a shaft by applying direct clamping force through the point. The knurled cup point bites into the mating surface to resist rotation and axial movement. Drive is via a 1\/8 inch hex key socket. This fastener meets ASME\/ANSI B18.3 and ASTM F912 standards and is sized in fractional inch measurements conforming to UNC thread standards.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for mechanical assemblies found in HVAC equipment, pump and motor shaft collars, fan hubs, and general industrial applications where a flush or recessed fastener is required. The Grade 8 alloy steel construction provides high tensile and torsional strength, making it appropriate for applications with vibration or significant torque loads. It installs without a protruding head, allowing components to seat flush against mating surfaces. Minimum order quantity is 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point for positive grip and resistance to rotation on shaft surfaces\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel for high strength in demanding mechanical environments\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch hex key drive for recessed installation in tight spaces\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows flush or sub-flush installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC set screw for use in any tapped through-hole or blind hole requiring a knurled cup point headless fastener conforming to ASME\/ANSI B18.3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 1\/8 inch hex key.
