It features a 3\/8-16 UNC thread and measures 3-1\/2 inches in overall length. The cup point geometry bites into the mating surface to resist rotational and axial movement under load. Drive engagement is through a 3\/16-inch hex key socket. Manufactured from alloy steel, this fastener meets the dimensional and performance requirements of ASME\/ANSI B18.3 and ASTM F912. It is used by machinists, millwrights, and maintenance technicians wherever a reliable, headless clamping fastener is required.\u003c\/p\u003e\n\u003cp\u003eCup point set screws in this thread and length range are commonly installed in shaft collars, shaft couplings, pulleys, sprockets, and similar rotating components across industrial, HVAC, and mechanical equipment. The 3\/8-16 coarse thread offers broad compatibility with standard tapped holes in both light and heavy mechanical assemblies. The alloy steel construction handles the clamping forces typical in power transmission and rotating equipment applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip bites into shaft or mating surface to resist movement under load\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex drive for standard Allen key or hex bit engagement\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high clamping force and durability\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below the surface for clearance-sensitive assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stocking fastener for any application requiring a 3\/8-16 UNC cup point set screw with a 3-1\/2-inch overall length and 3\/16-inch hex drive, conforming to ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 3\/16-inch hex key or Allen driver. De-energize and lock out all rotating equipment before installation or removal. Ensure the tapped hole is clean and free of debris before threading the screw. Do not exceed the torque capacity of the alloy steel fastener; consult applicable engineering references for proper seating torque based on application and surface hardness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 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: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 601280PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720749220146,"sku":"601280PR","price":1017.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da371b49ebcf14ad0c0baa611a54e450_32733470-edfa-4de2-b0ca-d85c7be4c352.jpg?v=1788568599","url":"https:\/\/voomisupply.com\/products\/value-collection-601280pr-set-screw-3-8-16-x-3-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
