Manufactured from alloy steel to the ASTM F912 material grade, this fastener provides the hardness and shear strength needed for high-load shaft and collar applications. It measures 4 inches in overall length with a 1-8 UNC thread and is driven with a 9\/16-inch hex key. The cup point digs into the mating surface to resist rotational and axial movement without requiring a through-hole. It conforms to ASME\/ANSI B18.3 dimensional standards.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in industrial and mechanical maintenance environments where shaft-to-hub connections, set collars, gears, pulleys, and similar components require a reliable locking fastener. The UNC thread form is the standard coarse-pitch pattern used across North American mechanical assemblies, making this screw a direct fit in a wide range of existing threaded bores. Machinists, millwrights, and maintenance technicians working on rotating equipment will find this size appropriate for larger-diameter shaft applications where a full 4-inch engagement depth is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface to resist rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated to ASTM F912 for high hardness and tensile strength\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread provides coarse-pitch engagement standard to North American mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch hex drive accommodates standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards for consistent fitment\u003c\/li\u003e\n  \u003cli\u003e4-inch overall length suits large-diameter or deep-bore shaft locking applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-form replacement or maintenance fastener for any threaded bore accepting a 1-8 UNC set screw conforming to ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a calibrated hex key or Allen driver sized to 9\/16 inch. De-energize and lock out all rotating equipment before accessing shaft fasteners. Do not over-torque the set screw against soft shaft materials without a hardened flat or keyway, as the cup point will permanently mark the shaft surface. Verify thread engagement depth and ensure the bore is clean and free of debris before driving.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8\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: 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: 9\/16 inches (0.5625 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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 601519BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716229923122,"sku":"601519BR","price":32.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8394391968776040de975bce3c994e9b_e36eee3b-3d2a-4ed1-834e-791660c5881b.jpg?v=1788523396","url":"https:\/\/voomisupply.com\/products\/value-collection-601519br-set-screw-1-8x4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
