Manufactured from Grade 8 alloy steel, this screw delivers high tensile and torsional strength suited to demanding industrial and trade applications. The 5\/16-18 UNC thread and 1\/4-inch overall length make it appropriate for compact assemblies with limited axial space. A 5\/32-inch hex key drive allows precise installation torque. Sold in a pack of 25 pieces, this fastener is a common stock item for maintenance shops, millwrights, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eCup point set screws are used wherever a shaft-to-hub connection must be secured without a protruding fastener head. Typical applications include motor shaft collars, pulley hubs, gear assemblies, and positioning fixtures in light to medium industrial equipment. The cup point geometry bites into the shaft surface to resist rotational and axial movement under load. This size is frequently encountered in HVAC blower wheel assemblies, pump impeller hubs, and general mechanical equipment service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface to resist axial and rotational movement\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch overall length suits compact, space-constrained assemblies\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex key drive for precise installation with common hand tools\u003c\/li\u003e\n  \u003cli\u003ePack of 25 pieces for bench stock and service van inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC set screw for use in any tapped 5\/16-18 through-hole or blind hole requiring a headless cup point fastener in Grade 8 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/32-inch hex key or Allen-type driver. Ensure the mating tapped hole is clean and free of debris before threading. De-energize and lock out any rotating equipment before servicing shaft-mounted components. Do not exceed the rated drive torque for the fastener size, and confirm thread engagement is adequate before applying load.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1\/4 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\u003eWeight\u003c\/strong\u003e: 0.0027 pounds (per piece)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\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: 88547591\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689481830706,"sku":"88547591","price":17.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cdc8bee4b8c7dd3bd037bb17a1c4bbc.jpg?v=1788260152","url":"https:\/\/voomisupply.com\/products\/value-collection-88547591-set-screw-5-16-18-x-1-4-in-cup-point-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
