Measuring 5\/8-18 thread size at 4 inches overall length, this screw is driven with a 5\/16-inch hex key and seats into the workpiece using its cup-shaped point to resist rotational and axial movement. Made from alloy steel and graded to ASTM F912, it meets the ASME\/ANSI B18.3 dimensional standard. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in shaft collars, set collar assemblies, and mechanical drives.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for industrial and commercial mechanical applications where a headless, flush-mount fastener is required. It is appropriate for use in rotating shaft assemblies, gear hubs, pulleys, and similar components where a protruding fastener head would create clearance or safety concerns. The 5\/8-18 unified fine thread (UNF) pitch provides tighter thread engagement compared to coarse thread equivalents, making it a preferred choice in precision or vibration-prone assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry concentrates clamping force onto the mating shaft surface for reliable grip\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF thread delivers fine thread engagement for precision fit and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e4-inch overall length accommodates deeper engagement in thick bosses or collar applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength suitable for demanding mechanical loads\u003c\/li\u003e\n  \u003cli\u003eASTM F912 material grade and ASME\/ANSI B18.3 dimensional standard ensure interchangeability with compliant hardware\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex drive accepts standard hex keys and hex-key T-handles common in shop and field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard hardware component for mechanical assemblies requiring a 5\/8-18 UNF cup point set screw conforming to ASME\/ANSI B18.3 and ASTM F912.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 5\/16-inch hex key or appropriate driver. De-energize and lock out any rotating equipment before installing or adjusting set screws. Thread the fastener by hand first to confirm proper thread engagement before applying torque. Do not substitute an incorrect thread pitch or drive size, as doing so can damage threads or result in inadequate 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\/8-18\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: 4 inches\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\u003eMaterial Grade\u003c\/strong\u003e: ASTM F912\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\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: 601433BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714323251506,"sku":"601433BR","price":21.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8394391968776040de975bce3c994e9b_eaefb23c-75ca-48e4-bc5a-233f9bb063d2.jpg?v=1788499503","url":"https:\/\/voomisupply.com\/products\/value-collection-601433br-set-screw-5-8-18-x-4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
