It measures 3 inches under the head and features partial threading along the shank. Manufactured from Grade 5 steel with a zinc-plated finish, this screw provides solid tensile strength and basic corrosion resistance for general industrial and mechanical assembly work. The unified fine thread (UNF) specification makes it appropriate for applications where precise thread engagement and resistance to loosening under vibration are required. Installers across HVAC, plumbing, and mechanical trades rely on Grade 5 fasteners for structural connections that demand consistent clamp load.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in residential and commercial mechanical equipment assembly, equipment mounting, and structural bracketing applications. Its partially threaded shank allows the unthreaded portion to act as a shoulder, which helps maintain alignment and distribute shear loads across the joint. The 3\/4-16 UNF thread is common in precision mechanical assemblies where fine thread pitch is specified by the original equipment design. This fastener is sold individually and is compatible with standard 3\/4-inch UNF hex nuts and threaded inserts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF thread for precise engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial threading for shoulder-style clamping\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction for reliable tensile and yield strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with standard hex head drive geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNF hex head cap screw compatible with 3\/4-16 threaded holes, hex nuts, and threaded inserts in mechanical equipment assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or trades professional using a correctly sized hex wrench or impact socket. Ensure the mating threaded hole or nut is clean and free of debris before installation. Follow the equipment manufacturer torque specifications for 3\/4-16 Grade 5 fasteners, as no specific torque value is included with this part. Reuse of fasteners that show signs of thread damage or deformation is not recommended.\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 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: HFI507503000NA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718146162994,"sku":"HFI507503000NA","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dad6721c1f9ebc88c0bf155dce69554c.jpg?v=1788550325","url":"https:\/\/voomisupply.com\/products\/value-collection-hfi507503000na-hex-cap-screw-3-4-16-x-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
