Set screws are headless fasteners threaded along their full length and tightened flush with or below a surface to secure a component — such as a collar, gear, or pulley — against a shaft. The half dog point provides a short cylindrical tip that seats into a mating hole or detent, resisting rotational and axial movement. This screw measures 1\/4 inch in both diameter and overall length and is driven with a 1\/8-inch hex key. It is installed by maintenance technicians and mechanical assemblers wherever positive shaft retention is required.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for mechanical assemblies in industrial, commercial, and trade applications where a secure, low-profile retention point is needed. The half dog point style is commonly specified when the mating shaft or hub includes a drilled detent hole for positive indexing and holding. The 1\/4-28 Unified Fine Thread (UNF) provides finer thread engagement and greater resistance to loosening under vibration compared to coarse-thread equivalents. Typical installations include drive shafts, encoder wheels, fan hubs, and similar rotating or sliding assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHalf dog point tip seats into drilled detents for positive shaft retention under vibration and axial load\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction delivers high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF thread offers fine pitch for precise clamping and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex drive accepts standard hex keys and ball-end drivers\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/4-inch overall length suits shallow boss and thin-hub applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF half dog point set screw conforming to ASME\/ANSI B18.3 and ASTM F912, suitable for use in any assembly specifying this thread size, point type, and drive configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/8-inch hex key or ball-end driver; ensure the tool is fully seated before applying torque to avoid rounding the drive. Power down and de-energize all rotating equipment before servicing any shaft-mounted component. Verify the mating shaft or hub includes a properly sized detent hole aligned to accept the half dog point. Do not substitute a cup or cone point in applications specifically designed for a dog point, as point geometry affects holding performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\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: 1\/4 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: 1\/8 inches (0.1250 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\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: 141111PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695639626034,"sku":"141111PR","price":3396.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b634c87017bfcc784d23a1f96fe245f.jpg?v=1788337106","url":"https:\/\/voomisupply.com\/products\/value-collection-141111pr-set-screw-1-4-28-x-1-4-in-half-dog","provider":"Voomi Supply","version":"1.0","type":"link"}
