Manufactured from alloy steel, this screw features a 5\/8-11 UNC thread and measures 2-1\/4 inches in overall length. It is driven by a 5\/16-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. The cup point geometry bites into the mating surface to resist axial and rotational movement, making it well suited for collars, hubs, pulleys, and shaft-mounted components. Installers in mechanical, HVAC, and industrial maintenance trades reach for this fastener when a set screw position must hold under vibration or load.\u003c\/p\u003e\n\u003cp\u003eThis set screw is appropriate for general industrial and mechanical assembly applications where a UNC 5\/8-11 thread is specified. Typical use cases include locking shaft collars, gear hubs, and sheaves in place on round stock. The cup point style is the most common point type for general clamping duty and works on both hardened and mild steel shafts. It is sized for applications calling for a longer engagement length relative to standard short-cup configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry provides positive bite into shaft material to resist rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction offers higher tensile strength compared to low-carbon steel fasteners\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread for broad compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex key drive allows use of standard L-keys and T-handle hex drivers\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design seats flush or below the surface for clearance-sensitive assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any tapped hole with a 5\/8-11 UNC thread specification, consistent with standard inch-series mechanical assemblies requiring a cup point set screw per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical and maintenance trades using a 5\/16-inch hex key or Allen driver. De-energize and lock out any rotating equipment before installing or adjusting set screws on shaft-mounted components. Verify the mating tapped hole is clean and free of debris before threading to avoid galling the alloy steel threads. Do not use an impact driver on set screws, as overdriving can strip the hex socket or damage the mating shaft surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/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 (Internal)\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\u003eThread Standard\u003c\/strong\u003e: UNC\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\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\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: 601393BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715225714994,"sku":"601393BR","price":44.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da371b49ebcf14ad0c0baa611a54e450_9822485b-1ec3-4d78-8c8e-015808d64629.jpg?v=1788510829","url":"https:\/\/voomisupply.com\/products\/value-collection-601393br-set-screw-5-8-11-x-2-1-4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
