Measuring 5\/16-18 thread size with an overall length of 3 inches, this fastener is driven by a 5\/32-inch hex key and seated fully below the surface of the mating part. Made from alloy steel and manufactured to ASTM F912 and ASME\/ANSI B18.3 standards, it delivers the hardness and shear strength needed in demanding industrial and mechanical applications. Machinists, millwrights, and maintenance technicians install this type of fastener in set screw collar, pulley, gear, and shaft-retention applications.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in rotating shaft assemblies, shaft collars, sprockets, couplings, and similar components where flush or below-surface fastener seating is required. The cup point geometry bites into the shaft surface to resist rotation and axial movement under load. It is commonly used in light manufacturing, HVAC equipment assemblies, conveyor systems, and general mechanical maintenance. Sold individually with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft material to resist rotation and axial displacement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM F912 material grade for high hardness and tensile strength\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standard for consistent fitment with standard hex keys\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex drive allows installation with a standard Allen wrench or hex key tool\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard (5\/16-18) for compatibility with common tapped holes in inch-measurement applications\u003c\/li\u003e\n  \u003cli\u003eOverall length of 3 inches accommodates deeper thread engagement requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any tapped hole conforming to 5\/16-18 UNC thread specification in inch-measurement mechanical assemblies, including shaft collars, pulleys, gears, and couplings that accept 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 machinists, millwrights, or qualified maintenance technicians using a calibrated hex key or Allen wrench of the correct 5\/32-inch drive size. Always de-energize and lock out rotating equipment before installing or removing set screws on live shafts. Do not over-torque the fastener, as this can damage the cup point or the shaft surface and reduce holding strength. Confirm the mating tapped hole thread is clean and free of debris before seating the screw.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cup Point\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 inch (0.1563 inch)\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\u003eThread Standard\u003c\/strong\u003e: UNC\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: 601250PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709141319986,"sku":"601250PR","price":1791.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02922f4f511f059830d6b0f212ba0eaf.jpg?v=1788451890","url":"https:\/\/voomisupply.com\/products\/value-collection-601250pr-set-screw-5-16-18-x-3in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
