Set screws are headless fasteners used to secure a component — such as a collar, gear, or pulley — onto a shaft by applying direct point pressure. This screw uses a square drive and a cup point tip, which bites into the mating surface to resist rotation and axial movement. It threads to the Unified National Coarse (UNC) standard and is measured by length under head. This fastener is suited for general mechanical assembly work performed by maintenance technicians, machinists, and trade professionals.\u003c\/p\u003e\u003cp\u003eThe 409046PR is appropriate for light-duty to moderate mechanical assemblies where a standard Grade 2 steel set screw meets the load and torque requirements. Cup point set screws are widely used in HVAC blower wheel hubs, motor shaft collars, and general industrial and commercial mechanical assemblies. The uncoated finish makes this screw suitable for dry or lightly oiled indoor environments. This SKU is sold in minimum order quantities of 100 pieces, making it practical for stocking in a service van or shop inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e3\/4 inch length measured under head for precise depth control\u003c\/li\u003e\n\u003cli\u003eCup point tip engages shaft surface to resist rotation and pull-out\u003c\/li\u003e\n\u003cli\u003eSquare drive socket for positive torque transfer with a square key wrench\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction suitable for general-duty mechanical fastening\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish; no added plating or coating that could affect dimensional tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose UNC set screw for standard 1\/4-20 tapped holes in mechanical assemblies requiring a cup point headless fastener.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall with the appropriately sized square drive key wrench; use of an incorrect drive tool can round the socket and damage the fastener. Ensure the mating shaft or component surface is clean and free of debris before tightening to allow the cup point to seat properly.
