Set screws are headless fasteners used to secure a component — such as a gear, pulley, or collar — against a shaft by applying direct clamping force at the point. The cup point digs into the mating surface to resist rotation and axial movement. This screw uses a square drive, which provides positive bit engagement under high torque. The 1\/4-20 UNC thread standard ensures compatibility with standard tapped holes across a wide range of assemblies. At 0.01 pounds per piece, the hardware is lightweight but made for sustained holding force in mechanical applications.\u003c\/p\u003e\n\u003cp\u003eCup point set screws in 1\/4-20 x 2 inch are commonly used in HVAC blower wheel hubs, motor shaft collars, pump couplings, and general mechanical assemblies. They are installed in residential and light commercial equipment wherever a shaft component must be locked in position without a protruding head. Technicians working on fan assemblies, damper shafts, or drive couplings will encounter this size regularly. The 2-inch length provides deeper thread engagement than standard short-body set screws, which is useful in thicker collars or extended boss applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface to resist rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003eSquare drive provides strong bit engagement and reduces cam-out under torque\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread fits standard tapped holes in common mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction, Grade 2, for reliable strength in typical service conditions\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head for deeper thread engagement in thick collars or hubs\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below surface, preventing interference with rotating components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 1\/4-20 UNC threaded cup point set screw with a 2-inch length, including HVAC blower assemblies, motor shaft collars, and mechanical drive components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSet screws of this type are installed by mechanical technicians and HVAC service professionals using a square drive bit or matching hex key where applicable. Ensure the shaft and tapped bore are clean and free of debris before installation. Do not over-drive — apply torque until the cup point seats firmly against the shaft without stripping the drive socket or thread. Lock out and tag out any equipment before servicing rotating assemblies that contain set screws.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Measurement Type\u003c\/strong\u003e: Length Under Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cup\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 409052PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699921584434,"sku":"409052PR","price":2431.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d715ee25bdcfb51a33e33a7d6c6b7bd5.jpg?v=1788383482","url":"https:\/\/voomisupply.com\/products\/value-collection-409052pr-set-screw-1-4-20-x-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
