Manufactured from alloy steel, this fastener provides high holding strength and resistance to loosening under vibration and torque loads. The cup point geometry bites into the mating shaft for a secure grip without requiring a through-hole. Driven with a 3\/16-inch hex key, the screw follows a 3\/8-16 UNC thread pattern and measures 3 inches in overall length. It meets ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in shaft collars, pulleys, gears, and similar rotating components.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in industrial and commercial mechanical assemblies where a headless, flush-mount fastener is required. Typical applications include securing hubs, sprockets, and couplings to shafts in conveyor systems, HVAC equipment drives, pump assemblies, and general power transmission setups. The 3\/8-16 UNC thread is a widely used coarse-thread size that is compatible with standard tapped holes in steel, cast iron, and aluminum components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into the shaft surface for positive holding without shaft damage\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength and hardness\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch overall length accommodates deeper shaft engagement requirements\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex drive for use with standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or stock set screw for any 3\/8-16 UNC tapped hole application requiring a cup point, headless fastener per ASME\/ANSI B18.3 and ASTM F912.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified maintenance technicians using a correctly sized 3\/16-inch hex key or Allen wrench. De-energize and lockout\/tagout any equipment before accessing shaft assemblies. Ensure the tapped hole is clean and free of debris before threading the screw.
