Manufactured from Grade 8 alloy steel, this screw delivers high tensile strength and hardness suitable for demanding industrial and trade applications. The 1\/4-28 UNF thread provides fine-pitch engagement for precise positioning, while the 3\/8-inch overall length keeps the profile compact for tight installations. Driven by a 1\/8-inch hex key, it seats flush or below the surface of the mating component, applying direct cup point pressure to lock shafts, collars, and pulleys in place. Licensed trades and maintenance technicians rely on this type of fastener across a wide range of equipment.\u003c\/p\u003e\u003cp\u003eCup point set screws like the MP40476-1 are used wherever a shaft, rod, or cylindrical component must be fixed relative to a hub, collar, gear, sprocket, or pulley. Common applications include HVAC blower wheel assemblies, motor shaft collars, pump impeller hubs, and general mechanical equipment found in both residential and light commercial installations. The fine UNF thread standard suits applications where precise torque and holding force are critical. This SKU ships in a package quantity of 50, making it practical for stocking in a service van or shop bin.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point tip bites into the mating shaft for firm, reliable holding force without full penetration\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction provides high tensile and proof strength\u003c\/li\u003e\n\u003cli\u003e1\/4-28 UNF fine-pitch thread for precise engagement and controlled clamp load\u003c\/li\u003e\n\u003cli\u003e1\/8-inch hex key drive fits standard Allen wrenches and hex bit drivers\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003cli\u003ePack of 50 units supports job-site and shop stocking needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-28 UNF cup point set screw conforming to ASME\/ANSI B18.3 and ASTM F912, suitable for use in any application requiring this thread size, point type, and drive specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 1\/8-inch hex key or Allen driver; confirm the driver is fully seated before applying torque to avoid rounding the socket. De-energize and lock out any equipment before accessing shaft or collar fasteners. Do not substitute a metric hex key, as an improperly sized driver can strip the socket. Follow the equipment manufacturer's assembly instructions for proper set screw seating depth and positioning.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\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: 3\/8 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: 1\/8 inches (0.1250 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: 50\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: MP40476-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711584633138,"sku":"MP40476-1","price":16.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6be30de352ae31f6f2b76d68f047b22a.jpg?v=1788477250","url":"https:\/\/voomisupply.com\/products\/value-collection-mp40476-1-cup-point-set-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
