Manufactured from Grade 8 alloy steel, it delivers high tensile strength and resistance to shear forces in demanding industrial and mechanical applications. The cup point geometry bites into mating surfaces to resist rotation and axial movement without requiring a through-hole. At 3\/8-24 UNF threading and 1-1\/2 inches overall length, this fastener is driven with a 3\/16-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians install these in hubs, collars, pulleys, and shafts across general manufacturing and MRO environments.\u003c\/p\u003e\n\u003cp\u003eThis set screw suits residential and commercial mechanical assemblies where a flush or recessed fastener is required. Typical applications include securing shaft collars, sprocket hubs, gear bores, and similar rotational components. The 3\/8-24 UNF thread pitch is suited for fine-thread applications where vibration resistance and precise clamping adjustment are important. This item is sold individually per package with a minimum order quantity of 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into mating shaft or surface for strong axial and rotational hold\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 UNF fine thread for precise adjustment and improved vibration resistance\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inches overall length suits deeper hub and collar engagement\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex drive compatible with standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF set screw for use in any threaded bore or tapped hole accepting a 3\/8-24 fine-thread fastener, including shaft collars, hubs, pulleys, and mechanical couplings requiring a cup point style.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated hex key or Allen driver sized to 3\/16 inch. Ensure the mating threaded bore is clean and free of debris before driving the screw. Do not exceed the rated torque capacity of the alloy steel fastener by using extended-handle drivers inappropriately. Always de-energize and lock out rotating machinery before servicing shaft-mounted components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-1\/2 inches (overall)\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 101491PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720887533874,"sku":"101491PR","price":5937.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd4db60e8490ef731ec7cad08001c994.jpg?v=1788570534","url":"https:\/\/voomisupply.com\/products\/value-collection-101491pr-set-screw-3-8-24-x-1-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
