This screw features a 1\/2-13 UNC thread with an overall length of 1-1\/4 inches and is driven by a 1\/4-inch hex key. The cup point geometry bites into mating surfaces to resist rotation and axial movement without requiring a through-hole. Manufactured from alloy steel to Grade 8 specifications, it delivers high tensile strength for demanding industrial and mechanical applications. Installation and removal require only a standard hex key, making it a practical choice for components that need periodic adjustment or repositioning.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for use in shaft-to-hub connections, collars, pulleys, sprockets, and similar rotating or stationary assemblies. It is appropriate for both light industrial and heavy-duty mechanical environments where a flush or recessed fastener is required. Licensed machinists, millwrights, and maintenance technicians typically install this hardware during equipment assembly or field maintenance. Its fractional inch sizing and UNC thread make it compatible with standard American inch-measurement tooling and tapped hole patterns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point design bites into mating surface to resist movement under load\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread for compatibility with standard inch-measurement tapped holes\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inches overall length suits medium-depth engagement applications\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction provides high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003e1\/4-inch hex drive accepts standard hex keys and Allen wrenches\u003c\/li\u003e\n\u003cli\u003eMeets 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 UNC inch-series set screw for use in any tapped 1\/2-13 threaded hole requiring a cup point, headless fastener per ASME\/ANSI B18.3 and ASTM F912.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 1\/4-inch hex key torqued to the assembly manufacturer's specification for the application. Ensure the mating shaft or surface is clean and free of burrs before seating the cup point. De-energize or lock out any rotating equipment before installing or removing set screws per applicable OSHA lockout\/tagout procedures. Do not exceed the rated tensile strength of the fastener by over-torquing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-1\/4 inches (overall)\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\/4 inch (0.2500 inch)\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\u003eThread Standard\u003c\/strong\u003e: UNC\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\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: 101577PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710818746674,"sku":"101577PR","price":1145.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a5932945a71af4785a36563a2d463e7.jpg?v=1788470962","url":"https:\/\/voomisupply.com\/products\/value-collection-101577pr-set-screw-1-2-13-x-1-1-4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
