Sized at 1\/4-20 UNC thread with a 1-3\/4 inch length under head, this screw is manufactured from Grade 2 alloy steel for dependable holding strength in demanding applications. The cup point bites into the mating surface to resist rotation and axial movement without the need for a bolt head. Driven with a square drive tool, it seats flush or below the surface of the workpiece. Machinists, millwrights, and industrial maintenance technicians install these in shafts, collars, pulleys, and similar components.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for use in general industrial and mechanical applications where a headless fastener is required. The 1\/4-20 UNC thread is a widely used coarse-thread standard compatible with standard tapped holes across a broad range of equipment. The cup point geometry is appropriate for applications on hardened or unhardened surfaces where a positive bite and resistance to loosening under vibration are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point geometry bites into mating surface to resist rotation and axial movement\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e1-3\/4 inch length under head for deeper engagement in thick collars or hubs\u003c\/li\u003e\n\u003cli\u003eGrade 2 alloy steel construction for reliable mechanical strength\u003c\/li\u003e\n\u003cli\u003eSquare drive reduces cam-out during installation and removal\u003c\/li\u003e\n\u003cli\u003eHeadless profile seats flush or below workpiece surface\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose headless set screw for mechanical assemblies using standard 1\/4-20 UNC tapped holes, including shafts, collars, pulleys, and hubs across industrial and trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with the appropriate square drive key or bit to the specified torque for 1\/4-20 fasteners per applicable mechanical standards. Ensure the mating hole is cleanly tapped and free of debris before threading the screw. Power down or de-energize any rotating equipment before servicing components that use set screws. Avoid over-torquing, which can strip the drive socket or damage the mating surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 (Under Head)\u003c\/strong\u003e: 1-3\/4 inches\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: Grade 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 409051PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690897768754,"sku":"409051PR","price":1831.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6fc717f1cad05d6aca98d1c3d2c4bb05.jpg?v=1788277230","url":"https:\/\/voomisupply.com\/products\/value-collection-409051pr-set-screw-1-4-20-x-1-3-4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
