Manufactured from Grade 2 alloy steel, it delivers solid holding strength in moderate-load applications. The screw measures 7\/8-9 thread size at 3-1\/2 inches in length, measured under the head, and follows the UNC thread standard. Drive type is square, which accepts a matching square key wrench for reliable torque transfer. Machinists, maintenance technicians, and mechanical contractors install this fastener when a positive bite into a shaft surface is required without permanent fastening.\u003c\/p\u003e\n\u003cp\u003eThis set screw fits standard mechanical assemblies where a cup point style is specified to grip into a shaft surface without through-drilling. Common applications include shaft collars, pulleys, sprockets, couplings, and similar power-transmission components in industrial, HVAC, and light mechanical settings. The 7\/8-9 UNC thread is a common fractional-inch coarse thread, compatible with tapped holes machined to that standard. Sold individually; minimum order quantity is 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft material for positive grip without permanent deformation\u003c\/li\u003e\n  \u003cli\u003eGrade 2 alloy steel construction provides reliable tensile strength for moderate clamping loads\u003c\/li\u003e\n  \u003cli\u003eSquare drive accepts a square key wrench for controlled torque application in tight installations\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard ensures compatibility with standard fractional-inch tapped holes\u003c\/li\u003e\n  \u003cli\u003eLength measured under head at 3-1\/2 inches for accurate fit in deep tapped holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or supplemental fastener for any mechanical assembly specifying a 7\/8-9 UNC cup point set screw with a square drive in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or mechanical maintenance technicians using a properly sized square drive key wrench. De-energize and lock out any rotating equipment before servicing shaft assemblies. Thread engagement should be verified to be full and clean before applying torque. Avoid cross-threading by hand-starting the screw before applying tool pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9\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: 3-1\/2 inches (measured under head)\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: Square\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 2\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: 0.02 pounds\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: 409144BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700347994418,"sku":"409144BR","price":77.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b05a5308bd6e0e2f7a73fd5bd72659f.jpg?v=1788389234","url":"https:\/\/voomisupply.com\/products\/value-collection-409144br-set-screw-7-8-9-x-3-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
