Set screws are fully threaded fasteners with no head, designed to secure a component — such as a pulley, gear, or collar — against a shaft by applying direct clamping force through the point. The cup point geometry bites into the mating surface for strong rotational and axial holding power. This fastener uses a 3\/8 inch internal hex (Allen) drive and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. It is suited for high-load industrial, mechanical, and HVAC equipment assembly applications where a flush or recessed fastener is required.\u003c\/p\u003e\u003cp\u003eThis set screw is used in mechanical assemblies across industrial, commercial, and residential applications. Common uses include securing shaft collars, sprockets, pulleys, and couplings in HVAC equipment, pumps, conveyor systems, and general machinery. The 3\/4-10 UNC thread and 3-inch overall length make it appropriate for heavier-duty assemblies requiring deep thread engagement. Installers working on rotating equipment, fan assemblies, or motor shaft components will find this size commonly specified in OEM and field-repair contexts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point tip bites into shaft surface for strong axial and rotational holding force\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n\u003cli\u003e3\/8 inch internal hex drive accepts standard Allen wrenches and hex keys\u003c\/li\u003e\n\u003cli\u003e3\/4-10 UNC thread standard ensures broad compatibility with tapped holes to that specification\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003cli\u003eFully threaded headless design allows flush or below-surface installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any tapped 3\/4-10 UNC threaded hole requiring a cup point set screw with a 3-inch overall length.

Ensure the mating shaft or bore surface is clean and free of debris before driving the screw to seat. Do not over-torque — refer to the equipment OEM torque specification for the applicable shaft diameter and application. Thread engagement and seating torque should comply with applicable ASME or equipment manufacturer guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3 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: Internal Hex (Allen)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 3\/8 inch (0.3750 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\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\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: 101679BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695652798770,"sku":"101679BR","price":67.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da371b49ebcf14ad0c0baa611a54e450_d9902e04-f092-4894-9b9e-6cdc90202f6c.jpg?v=1788337200","url":"https:\/\/voomisupply.com\/products\/value-collection-101679br-set-screw-3-4-10-x-3-in-cup-point-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
