Manufactured from alloy steel, this fastener delivers high torsional strength and resistance to backing out under vibration. It features a 7\/8-9 UNC thread form and measures 1 inch in overall length. The 1\/2-inch hex drive socket accepts a standard hex key for installation. Cup point geometry bites into the mating surface to resist rotational slippage, making this screw a reliable choice for couplings, collars, and set-screw-style locking arrangements across industrial and mechanical maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in industrial machinery, conveyor systems, pump and motor shaft assemblies, and general mechanical fabrication. The 7\/8-9 thread size places it in the heavy-duty fastener range, appropriate for larger-diameter shafting applications where significant axial and torque loads are present. Maintenance technicians, millwrights, and mechanical contractors typically install this fastener during equipment assembly or repair. It conforms to ASME\/ANSI B18.3 and ASTM F912 standards, ensuring dimensional consistency with other compliant hardware in the assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry for positive grip on mating shaft or surface\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread for compatibility with standard tapped collars and hubs\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex drive socket for use with standard hex keys or Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1 inch for medium-depth engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for any threaded assembly requiring a 7\/8-9 UNC cup point set screw with a 1\/2-inch hex drive, conforming to ASME\/ANSI B18.3 and ASTM F912 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/2-inch hex key or T-handle driver. Before installing or removing set screws in powered equipment, ensure the machine is fully de-energized and locked out per applicable LOTO procedures. Do not overtighten, as excessive force can deform the cup point or damage the mating shaft. Thread engagement and torque should follow the fastener manufacturer or equipment OEM guidelines for the specific assembly.\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\u003eOverall Length\u003c\/strong\u003e: 1 inch\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\/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\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: 101685BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698616860978,"sku":"101685BR","price":82.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da371b49ebcf14ad0c0baa611a54e450_3e6f323c-2548-4a22-8a45-30529a449ac5.jpg?v=1788365499","url":"https:\/\/voomisupply.com\/products\/value-collection-101685br-set-screw-7-8-9-x-1-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
