Manufactured from alloy steel, this fastener measures 7\/8-9 thread size by 1-1\/2 inches in overall length and is driven with a 1\/2-inch hex key. The cup point geometry bites into the mating surface to resist rotation and axial movement without requiring a through-hole. Conforming to ASME\/ANSI B18.3 and ASTM F912 standards, it suits demanding torque and load environments where dimensional accuracy and material strength are critical.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in a wide range of industrial and mechanical trade applications, including HVAC equipment assemblies, pump and motor shaft collars, sheaves, pulleys, and gears. It is appropriate for use in both light commercial and industrial settings wherever a reliable, headless locking fastener is specified. Machinists, millwrights, pipefitters, and HVAC\/R technicians routinely use cup point set screws in rotating equipment and drive-train assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry provides positive bite into shaft material for high resistance to rotation and axial slip\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction delivers the tensile and shear strength required in high-load mechanical joints\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread form for broad compatibility with standard tapped bores\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex drive accepts standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows flush or below-surface installation in rotating assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance fastener for mechanical assemblies requiring a 7\/8-9 UNC cup point set screw with a 1\/2-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist, millwright, or qualified mechanical technician. De-energize and lock out all rotating equipment before removing or installing set screws, in accordance with applicable OSHA lockout\/tagout procedures. Use a properly sized 1\/2-inch hex key to achieve full thread engagement and avoid rounding the drive socket. Do not reuse a set screw that shows signs of deformation, galling, or stripped threads.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-1\/2 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cup Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex (Internal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\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: 0.17 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 101691BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693470613810,"sku":"101691BR","price":98.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da371b49ebcf14ad0c0baa611a54e450_fb21c903-3f17-4748-b818-f93b00619931.jpg?v=1788312876","url":"https:\/\/voomisupply.com\/products\/value-collection-101691br-set-screw-7-8-9-x-1-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
