Manufactured from Grade 8 alloy steel, this fastener delivers high tensile and torsional strength suited to demanding industrial and trade applications. The cone point geometry bites into mating surfaces to resist rotation and axial movement, making it a reliable choice where vibration or dynamic loading is a concern. It accepts a 1\/8-inch hex key drive and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. Thread size is 1\/4-28 UNF with an overall length of 1\/4 inch.\u003c\/p\u003e\u003cp\u003eThis set screw is used in shaft-to-hub connections, collars, pulleys, gears, and similar mechanical components across industrial, HVAC, and general trade applications. The 1\/4-28 UNF thread is a fine-pitch designation that provides precise clamping force adjustment and resistance to loosening. It is well suited to light-gauge assemblies where fine thread engagement is preferred. Typically installed by machinists, maintenance mechanics, and field technicians in both residential and commercial mechanical systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCone point tip provides positive engagement into shaft or mating surface for strong axial and rotational hold\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction delivers high proof load and shear strength\u003c\/li\u003e\n\u003cli\u003e1\/4-28 UNF fine-pitch thread for precise torque control and vibration resistance\u003c\/li\u003e\n\u003cli\u003e1\/8-inch hex key drive for standard Allen wrench installation\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-28 UNF cone point set screw suitable for use in collars, hubs, gears, and other mechanical assemblies requiring a Grade 8 alloy steel fastener to ASME\/ANSI B18.3 specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 1\/8-inch hex key. De-energize or lock out any equipment before accessing the assembly in which this fastener will be installed. Do not exceed the rated drive strength of the hex socket by using impact tools or extended-lever adaptors. Inspect mating shaft or surface for burrs before seating the cone point to ensure proper engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 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: Cone\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\u003eThread Standard\u003c\/strong\u003e: UNF\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\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: 121125PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721104097586,"sku":"121125PR","price":3143.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f5040d52613d70c92ff41d4cf188068.jpg?v=1788573575","url":"https:\/\/voomisupply.com\/products\/value-collection-121125pr-set-screw-1-4-28-x-1-4-in-cone-point","provider":"Voomi Supply","version":"1.0","type":"link"}
