Set screws are headless fasteners that thread fully into a tapped hole and bear directly against a shaft, collar, or mating surface to resist rotational or axial movement. The cup point tip bites into the shaft for a strong mechanical lock without requiring a nut. Driven with a 1\/8 inch hex key, this screw suits applications where a flush or below-surface installation is required. Fabrication shops, maintenance technicians, and mechanical assemblers install these in production and repair work across a wide range of industrial and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in shaft collars, pulleys, gears, couplings, and similar components where a secure, non-protruding fastener is needed. The 1\/4-28 UNF thread provides finer thread engagement than coarse-thread equivalents, making it appropriate for applications requiring precise adjustment or where vibration resistance is a concern. It conforms to ASME\/ANSI B18.3 and ASTM F912 standards, which define the dimensional and mechanical requirements for hex socket set screws.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip bites into shaft surface for strong resistance to rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF thread for finer thread engagement and improved vibration resistance\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch internal hex drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design seats flush or below surface for clearance-sensitive assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF hex socket cup point set screw per ASME\/ANSI B18.3, suitable for use in any tapped hole or component accepting that thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/8 inch hex key or T-handle Allen driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread-locking compound if vibration is a concern in the application.
