Built from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under vibration and load. The 3\/8-24 UNF thread pattern provides fine-pitch engagement for precise positioning, while the cup point bites into the mating surface to resist rotation and axial movement. It is driven with a 3\/16-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. Sold in a pack of 25, it suits production, maintenance, and repair applications across mechanical, HVAC, and industrial settings.\u003c\/p\u003e\u003cp\u003eThis set screw is used in applications where a shaft, collar, pulley, or gear must be held in position on a shaft without a protruding head. The cup point style is a common choice in both light-duty and moderate-load assemblies where the fastener is expected to indent slightly into the shaft surface. Typical installers include millwrights, HVAC technicians securing blower wheel hubs, and maintenance mechanics working on rotating equipment. The UNF thread standard suits applications requiring tighter thread engagement than coarse-pitch alternatives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point geometry bites into mating surface for firm axial and rotational hold\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003e3\/8-24 UNF fine-pitch thread for precise depth adjustment and secure seating\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex drive for use with standard hex keys and Allen wrenches\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n\u003cli\u003ePack of 25 suits both single repairs and small production runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-24 UNF cup point set screw conforming to ASME\/ANSI B18.3, suitable for any threaded bore accepting a 3\/8-24 headless set screw of 1-inch overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/16-inch hex key or T-handle driver. De-energize and lock out any equipment before accessing rotating components. Thread the screw by hand first to confirm thread engagement and avoid cross-threading. Do not exceed the torque capacity of the hex key socket, as over-driving can strip the drive recess or damage the mating bore.\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: 1 inch\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 inch (0.1875 inch)\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: MP40488-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701556379954,"sku":"MP40488-1","price":22.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8fde8beac904b872c8e5b516b687afa.jpg?v=1788401428","url":"https:\/\/voomisupply.com\/products\/value-collection-mp40488-1-set-screw-3-8-24-x-1-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
