Manufactured from Grade 8 alloy steel, this screw delivers high tensile strength suited for industrial and trade applications. The 5\/16-18 UNC thread and 3\/8-inch overall length make it a compact, high-load fastener. Drive engagement is through a 5\/32-inch hex key socket. Each package contains 25 pieces, making it practical for service kits, maintenance stockrooms, and production use. HVAC technicians, pipefitters, electricians, and mechanical contractors commonly use cup point set screws to secure pulleys, collars, and hubs.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in rotating shaft assemblies, motor couplings, shaft collars, and mechanical drive components found in residential and light commercial HVAC equipment, pumps, fans, and conveying systems. The cup point geometry bites into the shaft surface to resist rotational and axial movement. It is installed with a standard hex key or Allen driver and is appropriate wherever a headless fastener is required in a tapped hole application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip bites into shaft material for positive grip against rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread standard for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch overall length suits compact shaft collar and hub applications\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex drive allows use with standard hex keys and Allen drivers\u003c\/li\u003e\n  \u003cli\u003e25-piece pack suitable for service kits and stocking maintenance inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC-thread cup point set screw for use in any tapped 5\/16-18 hole requiring a headless fastener in mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/32-inch hex key or Allen driver. De-energize and lock out all rotating equipment before servicing shaft assemblies. Ensure the mating tapped hole is clean and free of debris before threading the screw in by hand to avoid cross-threading. Do not exceed the torque capacity of the hex socket; use calibrated torque tools where the application demands repeatable clamping force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\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: 5\/32 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\u003eThread Standard\u003c\/strong\u003e: UNC\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: 0.0045 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: 88547351\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689383297330,"sku":"88547351","price":16.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fab44a08a5801c93cfff983413bcee7.jpg?v=1788258631","url":"https:\/\/voomisupply.com\/products\/value-collection-88547351-cup-point-set-screw-5-16-18-x-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
