Sized at 3\/4-16 (Unified National Fine thread) with a 3-1\/4 inch length under head, this screw features partial threading and an uncoated finish. It conforms to ASME B18.2.1 and SAE J429 standards, making it a recognized option for critical structural and mechanical assemblies. Sold in a package quantity of 25, the C703519 is suited for shops, maintenance crews, and field technicians who need a reliable supply of heavy-duty fasteners on hand.\u003c\/p\u003e\u003cp\u003eGrade 8 hex head cap screws of this size are commonly used in heavy equipment assembly, industrial machinery, structural steel connections, and high-load mechanical joints. The 3\/4-16 UNF thread pitch provides finer thread engagement compared to coarse-thread variants, which is preferred where vibration resistance or precise torque control is required. The uncoated finish is standard for applications where the joint will be lubricated, painted over, or used in controlled environments without exposure to corrosive conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction meets SAE J429 for high tensile strength and proof load requirements\u003c\/li\u003e\n\u003cli\u003e3\/4-16 Unified National Fine (UNF) thread for tighter thread engagement and improved vibration resistance\u003c\/li\u003e\n\u003cli\u003e3-1\/4 inch length under head suits medium-to-long reach fastening applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for controlled clamping force and shear load capacity\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fit with standard hex nuts and washers\u003c\/li\u003e\n\u003cli\u003eSold in a 25-piece package to support production, maintenance, and repair work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with 3\/4-16 UNF hex nuts, flat washers, and lock washers conforming to ASME and SAE dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical or maintenance technicians familiar with fastener torque requirements for Grade 8 hardware. De-energize, depressurize, or lock out any equipment before servicing fastened joints. Use a calibrated torque wrench and apply the appropriate torque value per the equipment manufacturer's specifications or applicable engineering standards. Do not mix Grade 8 fasteners with lower-grade nuts or hardware, as mismatched grades can result in joint failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF (Unified National Fine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\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: C703519\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700743373106,"sku":"C703519","price":93.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c28eb2d4d9e32575ba55f00249d822d4_5e6ed103-3685-4d42-8e20-f2fe86f3942d.jpg?v=1788394677","url":"https:\/\/voomisupply.com\/products\/value-collection-c703519-hex-cap-screw-3-4-16-grade-8-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
