At 3\/16 inches in overall length, this fastener uses a 1\/8-inch hex drive and features a cone point tip that bites into mating surfaces to resist rotation and axial movement. It is manufactured to ASME\/ANSI B18.3 and ASTM F912 standards, ensuring dimensional consistency and mechanical performance. Trades and maintenance professionals use this screw when positive locking force is required in collars, hubs, pulleys, and shaft assemblies across mechanical and industrial equipment.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in light industrial, HVAC, plumbing, and general mechanical applications where a compact, headless fastener is needed to secure a component to a shaft or within a threaded bore. The cone point geometry concentrates clamping load at a single contact point, making it well suited for permanent or semi-permanent assemblies. The 1\/4-20 UNC thread standard ensures broad compatibility with standard tapped holes found in common mechanical components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCone point tip concentrates load for strong shaft engagement and rotation resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex drive accepts standard hex keys for installation in confined spaces\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread fits widely used standard tapped hole sizes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eCompact 3\/16-inch overall length suits shallow-bore and tight-clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock set screw for any application requiring a 1\/4-20 UNC, 3\/16-inch overall length cone point set screw with a 1\/8-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a calibrated 1\/8-inch hex key or Allen wrench; ensure the key is fully seated before applying torque to avoid rounding the drive. Power down or de-energize any equipment before accessing rotating components such as pulleys, collars, or shaft hubs. Verify the mating shaft or bore surface is clean and free of debris before seating the cone point. Follow applicable ASME or equipment manufacturer guidelines for thread engagement and fastener reuse.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\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 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\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: 604221PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722087924018,"sku":"604221PR","price":3047.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ed0c7e42ffe032271bbdfdb407887df.jpg?v=1788585458","url":"https:\/\/voomisupply.com\/products\/value-collection-604221pr-set-screw-1-4-20-x-3-16-in-cone-point","provider":"Voomi Supply","version":"1.0","type":"link"}
