This fully threaded headless fastener measures 3\/16 inches in overall length and is driven with a 1\/16-inch hex key. Cup point geometry bites into the mating shaft surface to resist rotation and axial movement under load. Grade 8 alloy steel delivers high tensile and torsional strength, making this screw suited for applications where vibration or torque would loosen a softer fastener. Meets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards. Machinists, maintenance technicians, and assemblers use this fastener in precision mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in small-diameter shaft-to-hub connections found in motors, gearboxes, pulleys, collars, and similar mechanical components. The fine 5-44 UNF thread pitch provides greater thread engagement per unit length compared to coarse-thread equivalents, which is advantageous in thin hubs or short engagement depths. Typical applications include instrument mechanisms, small electric motor shafts, and precision positioning assemblies where a compact headless fastener is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-44 UNF thread for high thread engagement in tight spaces\u003c\/li\u003e\n  \u003cli\u003eCup point tip digs into shaft surface to resist rotation and axial slip\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e1\/16-inch hex drive for use with standard hex keys or Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 standards\u003c\/li\u003e\n  \u003cli\u003eHeadless profile sits flush or below surface when fully seated\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or drop-in fastener for mechanical assemblies requiring a 5-44 UNF headless cup point set screw with a 1\/16-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/16-inch hex key torqued by hand to the assembly specification. Ensure the mating shaft and hub threads are clean and free of burrs before installation. Do not overtighten, as the small thread form is susceptible to stripping. Always de-energize or lock out any rotating equipment before accessing set screw locations per applicable safety procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-44\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/16 inches\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\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: 101129PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710776901938,"sku":"101129PR","price":3109.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d61b73f55ade86e5d2e3df11c65bd09.jpg?v=1788470442","url":"https:\/\/voomisupply.com\/products\/value-collection-101129pr-set-screw-5-44-x-3-16-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
