Set screws of this type are headless fasteners used to lock a component — such as a collar, gear, or pulley — onto a shaft by bearing directly against the shaft surface. The knurled cup point increases grip and bite into the mating surface, reducing slippage under vibration or torque. Drive is a 3\/16 inch hex key socket. Thread form is UNF (Unified National Fine), which provides tighter thread engagement than coarse thread in the same diameter. These screws conform to ASME\/ANSI B18.3 and ASTM F912 standards.\u003c\/p\u003e\n\u003cp\u003eKnurled cup point set screws in 3\/8-24 UNF are commonly used in industrial and mechanical assemblies where positive shaft retention is required. Typical applications include motor shaft collars, conveyor components, HVAC blower wheel hubs, and general mechanical drive assemblies in both commercial and light industrial settings. The Grade 8 alloy steel construction suits applications where higher tensile strength is required compared to standard steel set screws. This package contains 25 pieces, making it practical for stocking or multi-unit installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point design bites into shaft surface for increased resistance to rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile strength for demanding mechanical applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 UNF thread offers finer thread pitch for greater clamping force and precision adjustment\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex key drive for standard Allen wrench installation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package suitable for stocking or batch installation work\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 hole or component accepting a 3\/8-24 thread with ASME\/ANSI B18.3 dimensional compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/16 inch hex key (Allen wrench). Ensure the mating threaded bore is clean and free of debris before driving the screw to seating. De-energize and lock out any rotating equipment before accessing shaft-mounted components. Do not exceed the torque rating of the threaded bore material, particularly when installing into aluminum or soft alloy housings.\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: 0.5 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Knurled 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  \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: 40546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715335323954,"sku":"40546","price":42.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/263bbc746cd8aedeb48495be390b238f.jpg?v=1788512240","url":"https:\/\/voomisupply.com\/products\/value-collection-40546-set-screw-3-8-24-x-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
