It features a knurled cup point designed to grip shaft surfaces and resist rotational loosening under load. Drive engagement is through a 3\/16-inch hex key socket. The knurled cup point bites into the mating surface, providing higher holding power than a plain cup point. This fastener meets ASME\/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance. Sold in a package of 25, it suits production shops, MRO stockrooms, and field service kits that require consistent Grade 8 performance in threaded assemblies.\u003c\/p\u003e\n\u003cp\u003eGrade 8 alloy steel set screws in this thread size are used across a wide range of mechanical assemblies including shaft collars, pulleys, sprockets, gears, and couplings in industrial, HVAC, and mechanical equipment applications. The 3\/8-24 UNF fine thread pitch offers tighter clamp control in applications where vibration resistance and precise axial positioning matter. The package quantity of 25 makes this suitable for both single-job use and bin-stock replenishment in maintenance and fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point provides aggressive grip on shaft surfaces to resist loosening under vibration and torque\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction delivers high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 UNF fine thread for precise engagement and vibration-resistant clamping\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex key drive for standard Allen wrench installation\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003ePackage of 25 units supports both single-job use and bulk MRO stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit fastener for any mechanical assembly requiring a 3\/8-24 UNF Grade 8 alloy steel set screw with a knurled cup point and 3\/16-inch hex key drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/16-inch hex key or Allen wrench. Ensure the mating threaded bore is clean and free of debris before threading the screw in by hand to avoid cross-threading. De-energize and lock out any rotating equipment before servicing assemblies that contain these fasteners. Do not exceed the fastener's rated clamp load by using extensions or impact tools on the hex key.\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\u003eOverall Length\u003c\/strong\u003e: 3\/4 inches\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\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: 40547\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691722998066,"sku":"40547","price":29.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/036e62934e0c3d148ed3b2c72ee71f27.jpg?v=1788288894","url":"https:\/\/voomisupply.com\/products\/value-collection-40547-set-screw-3-8-24-x-3-4-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
