Grade 8 is the highest commonly specified SAE grade for inch-series fasteners, offering minimum proof strength of 120,000 psi and tensile strength of 150,000 psi — making this screw appropriate for high-stress mechanical assemblies. The 3-inch length under head and UNF (Unified National Fine) thread pitch of 16 threads per inch provide strong clamping force in steel-to-steel and flange-mounted applications. Zinc plating provides baseline corrosion resistance in moderately exposed environments. This item ships in a pack of 5.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used by millwrights, pipefitters, HVAC equipment installers, and maintenance technicians assembling or servicing heavy mechanical equipment, structural mounts, equipment bases, and flange connections. The fine thread pitch suits applications where precise torque control and vibration resistance are priorities, such as motor mounts, compressor hold-downs, and structural brackets in mechanical rooms. Grade 8 steel makes it suitable for demanding load-bearing joints where standard Grade 5 hardware is insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high-tensile-strength bolted joints\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 UNF fine thread for precise clamping and vibration resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for shear load transfer across unthreaded grip length\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for moderate corrosion resistance in indoor and semi-exposed installations\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A354 BD standard for mechanical and chemical requirements\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 5 with a minimum order quantity of 1 pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/4-16 UNF tapped holes or with matching 3\/4-16 UNF nuts in inch-system mechanical assemblies requiring Grade 8 fastener specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified millwrights, pipefitters, or maintenance technicians using standard hex sockets or wrenches sized for 3\/4-inch hex head fasteners. Always torque to the specification listed in the equipment manufacturer's service documentation for Grade 8 UNF fasteners at this diameter. De-energize and lock out all equipment per OSHA LOTO procedures before servicing any bolted joint. Do not substitute Grade 8 hardware with lower-grade fasteners in structural or high-load applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 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: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A354 BD\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: 5 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: MPKP45135\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718364889394,"sku":"MPKP45135","price":33.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a2526fd790f2f3c933d1ceedc2404cc_ebca92f0-3f2c-451c-8517-818539e16f57.jpg?v=1788552541","url":"https:\/\/voomisupply.com\/products\/value-collection-mpkp45135-hex-cap-screw-3-4-16-x-3-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
