It features a 5-40 UNC thread in a 5\/8-inch overall length and is driven with a 1\/16-inch hex key. The cup point digs into the mating surface to resist rotation and axial movement under load. Manufactured from Grade 8 alloy steel, this screw delivers high tensile and torsional strength in compact fastening applications. Machinists, maintenance technicians, and assemblers install these in light-duty mechanical assemblies, instrument hardware, and precision equipment where a low-profile fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for residential and commercial mechanical assemblies requiring a fine-thread, small-diameter fastener. Typical applications include collar and gear retention on small shafts, setscrew locking in instrument enclosures, and general mechanical assembly work. The Grade 8 alloy steel construction makes it appropriate for applications with moderate vibration or load demands. It conforms to ASME\/ANSI B18.3 and ASTM F912, making it a standard fit for engineering and maintenance environments that specify these fastener standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread for fine-pitch engagement in small-diameter applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch overall length suitable for moderate-depth socket engagement\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into mating surface to resist rotation and axial shift\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e1\/16-inch hex drive for use with standard hex key sets\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fit set screw for mechanical assemblies requiring a 5-40 UNC thread, cup point, and ASME\/ANSI B18.3 or ASTM F912 compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a 1\/16-inch hex key. Ensure the mating shaft or housing bore is clean and free of debris before driving the screw. Do not exceed the rated drive torque for the 5-40 thread class, and avoid over-tightening, which can strip the small-diameter thread. Consult applicable mechanical assembly standards when installing in load-bearing or vibration-prone applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\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: 5\/8 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: 1\/16 inches (0.0625 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\u003eMeasurement Type\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: 101123PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689717596466,"sku":"101123PR","price":3197.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da371b49ebcf14ad0c0baa611a54e450.jpg?v=1788263395","url":"https:\/\/voomisupply.com\/products\/value-collection-101123pr-set-screw-5-40-x-5-8-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
