Manufactured from Grade 8 alloy steel, it provides high tensile strength and resistance to shear forces encountered in demanding industrial and trade environments. The screw measures 5\/16-18 UNC thread by 5\/16 inches overall length and is driven with a 5\/32 inch hex key. It conforms to ASME\/ANSI B18.3 and ASTM F912 standards, making it a code-compliant choice for precision fastening work wherever a half dog point is required to engage a drilled detent or flat on a shaft.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in rotating equipment, motor shaft collars, couplings, pulleys, and mechanical drive components found in HVAC equipment, pump assemblies, and general industrial machinery. The half dog point style — featuring a reduced-diameter cylindrical tip — locates securely into a mating hole or flat on a shaft without full penetration, allowing for controlled positional holding with easy disassembly. Installers in mechanical, HVAC, and industrial maintenance trades commonly use this fastener during equipment assembly and field repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHalf dog point tip engages drilled detents or shaft flats for positive, repeatable positioning\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction delivers high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e5\/32 inch internal hex drive allows torque application with a standard Allen key\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eFractional inch sizing for straightforward field identification and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series set screw for use in any tapped 5\/16-18 UNC threaded hole requiring a half dog point style fastener in mechanical assemblies and equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical or maintenance trades using a 5\/32 inch hex key or Allen wrench. Always de-energize and lock out rotating equipment before installing or removing set screws in shaft collars or couplings, following applicable OSHA lockout\/tagout procedures. Ensure the mating detent or flat on the shaft is properly aligned with the half dog point before tightening. Do not exceed the rated proof load of the fastener; apply torque gradually and evenly.\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\u003eLength\u003c\/strong\u003e: 5\/16 inches (overall)\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 (internal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 5\/32 inches (0.1563 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\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  \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: 141115PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696412688690,"sku":"141115PR","price":3395.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8f823d37339f6ea9f1e4bcdc6e78440.jpg?v=1788342390","url":"https:\/\/voomisupply.com\/products\/value-collection-141115pr-set-screw-5-16-18-x-5-16-in-half-dog","provider":"Voomi Supply","version":"1.0","type":"link"}
