Sized at 1\/2-13 UNC thread with an overall length of 1-1\/4 inches, it is driven by a 1\/4 inch hex key. Manufactured from Grade 8 alloy steel, it delivers high tensile strength suitable for demanding industrial and mechanical applications. The cup point geometry bites into the mating surface to resist rotational and axial movement without requiring a head, making it ideal for use in collars, pulleys, gears, and shafts. Machinists, millwrights, and maintenance technicians typically install this fastener.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for use in general industrial machinery, conveyor systems, shaft-to-hub connections, and mechanical drive assemblies where a headless fastener is required to lock a component onto a shaft or within a housing. The 1\/2-13 UNC thread is a common coarse-thread designation found across a wide range of standard mechanical components. Compliance with ASME\/ANSI B18.3 and ASTM F912 standards makes it a direct fit for applications requiring documented fastener specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point geometry grips mating shaft surfaces to resist rotation and axial movement\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003e1\/4 inch hex key drive for controlled torque application in tight spaces\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003cli\u003eHeadless design allows flush or sub-flush installation in collars and hubs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and aftermarket replacement set screw for standard 1\/2-13 UNC tapped holes in mechanical collars, shaft couplings, pulleys, gears, and similar hardware conforming to ASME\/ANSI B18.3 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 1\/4 inch hex key or Allen driver. De-energize and lock out all rotating machinery before removing or installing set screws per applicable OSHA lockout\/tagout procedures. Verify the tapped hole is clean and free of debris before threading in the fastener. Do not exceed the torque capacity of the hex socket drive or the rated strength of the mating tapped material.\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\u003eOverall Length\u003c\/strong\u003e: 1-1\/4 inches\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 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: UNC\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: 40418\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693914620210,"sku":"40418","price":49.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e07a3950e3d83be1835315559bd4f55e.jpg?v=1788319005","url":"https:\/\/voomisupply.com\/products\/value-collection-40418-cup-point-set-screw-1-2-13-x-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
