It features a 5\/8-18 UNF thread and measures 1-3\/4 inches in overall length. The cup point digs into the mating surface to resist rotation and axial movement without a protruding head. Driven by a 5\/16-inch hex key, the alloy steel construction provides the tensile strength needed in high-load applications. This screw meets ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians working on shafts, collars, pulleys, and similar mechanical components are the typical installers.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for use in industrial and commercial mechanical assemblies where a headless fastener is required to lock components onto shafts or within bores. The 5\/8-18 UNF thread is a fine-pitch specification commonly found in precision shaft-locking applications across manufacturing, HVAC equipment, pump assemblies, and power transmission components. The cup point style is the most widely used point geometry for general-purpose shaft retention.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-18 UNF fine-pitch thread for precise shaft engagement\u003c\/li\u003e\n\u003cli\u003eCup point geometry bites into shaft surface to resist rotation and axial shift\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex drive compatible with standard hex keys and T-handle drivers\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush or below surface for clearance-sensitive applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard headless cup point set screw for use in mechanical assemblies requiring a 5\/8-18 UNF threaded fastener with a 5\/16-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a calibrated 5\/16-inch hex key or Allen driver. Always de-energize and lock out equipment before servicing any shaft or rotating assembly. Verify thread engagement depth and confirm the cup point seats fully against the shaft surface before applying final torque. Alloy steel set screws should not be used in applications requiring corrosion resistance without appropriate protective coatings or material substitution.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\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: 1-3\/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\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\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: 601424BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693694943538,"sku":"601424BR","price":46.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da371b49ebcf14ad0c0baa611a54e450_de94cd47-f210-455e-a3ee-d6cfd5e536c9.jpg?v=1788316193","url":"https:\/\/voomisupply.com\/products\/value-collection-601424br-set-screw-5-8-18-x-1-3-4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
