Manufactured from Grade 8 alloy steel, it delivers high tensile strength and hardness suitable for demanding industrial and trade environments. The 1\/4-20 UNC thread and 3\/8-inch overall length make it a compact fastener commonly installed in collars, hubs, pulleys, and shafts. Drive engagement is achieved with a 1\/8-inch hex key. This fastener meets ASME\/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance for precision applications.\u003c\/p\u003e\u003cp\u003eThis set screw is used across a wide range of mechanical, HVAC, and industrial applications where a shaft or component must be secured to a mating part without a protruding head. The cone point geometry bites into the mating surface, providing strong rotational and axial holding force. It is well suited for permanent or semi-permanent installations where vibration resistance is a priority. Machinists, millwrights, HVAC technicians, and industrial maintenance professionals routinely install this type of fastener.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCone point geometry for strong bite and positive locking into mating shaft surfaces\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile strength and wear resistance\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC thread form for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e1\/8-inch hex drive for use with standard hex keys and Allen wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 UNC cone point set screw suitable for use in any tapped hole conforming to 1\/4-20 thread specifications where a headless, flush-mount fastener is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 1\/8-inch hex key or Allen wrench. Ensure the mating component is fully secured and aligned before tightening. De-energize or lock out any machinery before servicing assemblies that contain set screws. Avoid overtightening, as cone point set screws can permanently deform soft mating surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/8 inches (overall)\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\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\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: 121103PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714934604082,"sku":"121103PR","price":3505.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b12a9569a9e91fcfbcc0a6f1618effb4.jpg?v=1788508061","url":"https:\/\/voomisupply.com\/products\/value-collection-121103pr-set-screw-1-4-20-x-3-8-in-cone-point","provider":"Voomi Supply","version":"1.0","type":"link"}
