Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under vibration and torque loads. The 3\/8-24 UNF thread pitch provides fine thread engagement for controlled clamping force, while the 3\/4-inch overall length suits a range of hub depths. Driven by a 3\/16-inch hex key, it conforms to ASME\/ANSI B18.3 and ASTM F912 standards. Each package contains 25 pieces.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for use in rotating shaft assemblies, sheaves, sprockets, gears, and shaft collars where a recessed drive and flush or sub-flush seating are required. The cup point bites into the shaft surface to resist axial and rotational movement, making it a common choice in conveyor systems, motor shafts, and general mechanical power transmission assemblies. It is appropriate for both light industrial and heavy-duty applications where Grade 8 strength is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003eCup point geometry bites into shaft surface for positive anti-rotation grip\u003c\/li\u003e\n\u003cli\u003e3\/8-24 UNF fine thread for precise clamping adjustment\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex key drive for recessed installation in tight clearances\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003cli\u003eSold in a 25-piece package to support job-site and shop inventory needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNF set screw for use in any threaded bore sized for 3\/8-24 thread, including shaft collars, hubs, couplings, and similar mechanical components requiring a cup point headless fastener.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/16-inch hex key or Allen driver; ensure the driver is fully seated before applying torque to avoid rounding the socket. De-energize all rotating machinery and lock out power before servicing any shaft assembly. Do not reuse set screws that show signs of deformation at the cup point or thread damage. Follow applicable machinery and mechanical standards for fastener seating and inspection intervals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 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: 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\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\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\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: MP40488\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716356997426,"sku":"MP40488","price":18.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7af4f202f88d4d1df1fff0f74bfa0172.jpg?v=1788524806","url":"https:\/\/voomisupply.com\/products\/value-collection-mp40488-set-screw-3-8-24-x-3-4-in-cup-point-gr8","provider":"Voomi Supply","version":"1.0","type":"link"}
