Sized at 5\/8-11 thread with an overall length of 5\/8 inches, this fastener is driven by a 5\/16-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. The half dog point extends partially beyond the set screw tip, providing a short cylindrical pilot that locates into a drilled hole or groove on the mating shaft for positive positioning and resistance to rotation. Machinists, maintenance technicians, and industrial assemblers typically install these fasteners in mechanical assemblies.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for use in shaft collars, pulleys, sprockets, gears, and similar mechanical components requiring a positive-locking fastener. The half dog point is particularly useful in applications where the fastener must register into a drilled detent on the shaft, preventing axial and rotational movement under load. Typical installation environments include industrial machinery, drive train assemblies, and general manufacturing maintenance. Sold individually per unit with a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHalf dog point design provides a short cylindrical pilot for positive shaft location and rotation resistance\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction delivers high tensile and torsional strength\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex drive for standard hex key installation\u003c\/li\u003e\n\u003cli\u003eUNC thread standard (5\/8-11) ensures broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 for dimensional and mechanical compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC-thread set screw for use in any tapped hole or component accepting a 5\/8-11 thread, half dog point fastener per ASME\/ANSI B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using a 5\/16-inch hex key or Allen driver. Ensure the mating component has a properly drilled and positioned detent hole on the shaft before driving the half dog point fully into engagement. De-energize and lock out any machinery before servicing components that contain set screws. Do not exceed the torque capacity of the fastener or the mating material, and verify thread engagement is adequate for the applied load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Half Dog\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: Grade 8\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\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: 0.02 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: 606421BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693357498674,"sku":"606421BR","price":52.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46f71b404aae04351bcb098227bbb1d9.jpg?v=1788311169","url":"https:\/\/voomisupply.com\/products\/value-collection-606421br-set-screw-5-8-11-x-5-8-half-dog-point","provider":"Voomi Supply","version":"1.0","type":"link"}
