Set screws are headless fasteners used to secure a component — such as a collar, gear, or pulley — against a shaft by applying direct pressure through the cup point into the mating surface. This screw is driven with a 1\/8-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards, making it suitable for applications where dimensional consistency and material strength are critical. Grade 8 alloy steel provides high tensile strength for demanding mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in light industrial, mechanical, and equipment maintenance applications. Typical install scenarios include securing shaft collars, sprockets, and pulleys on rotating equipment, as well as locking adjustment mechanisms on machinery frames. The cup point configuration bites into the mating surface to resist rotational loosening. It is sized for 1\/4-20 UNC threads and measures 7\/8 inches in overall length, fitting standard tapped holes in steel, cast iron, and aluminum components across a wide range of assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip bites into mating surface for strong rotational and axial hold\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength in demanding applications\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex drive for use with standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread standard for compatibility with commonly tapped holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch overall length suits moderate-depth tapped shaft and hub applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC cup point set screw for use in any tapped hole conforming to ASME\/ANSI B18.3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSet screws of this type are typically installed by machinists, millwrights, or maintenance technicians using a 1\/8-inch hex key. Ensure the shaft or mating surface is clean and free of debris before installation. De-energize and lock out all rotating equipment before servicing any shaft-mounted component. Do not over-drive the screw beyond the point of firm seating, as excessive force can strip the tapped hole or damage the drive socket.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 7\/8 inches (overall length)\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\u003eDrive Size\u003c\/strong\u003e: 1\/8 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\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: 101323PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717615583538,"sku":"101323PR","price":2700.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9fca3f2c02f6ce55acd7f884f879d50.jpg?v=1788543440","url":"https:\/\/voomisupply.com\/products\/value-collection-101323pr-set-screw-1-4-20-x-7-8-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
