Manufactured from Grade 8 steel with no finish coating, this screw delivers a minimum tensile strength of 150,000 psi as required by Grade 8 classification under ASME B18.2.1. The 3\/4-16 thread designation indicates a 3\/4-inch nominal diameter with 16 threads per inch on a UNF (Unified National Fine) pitch. The screw measures 3 inches under the head and is partially threaded, leaving a smooth shank section near the head to improve shear resistance in bolted joint applications. Each package contains 25 pieces.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for heavy equipment assembly, structural connections, automotive and agricultural machinery, and industrial fabrication where high clamping force and fatigue resistance are required. The UNF thread form provides finer pitch engagement than coarse-thread equivalents, making it a common choice for joints subject to vibration or for applications requiring precise torque control. Partially threaded construction is standard practice when the grip length must remain unthreaded to bear shear load across a joint interface. These screws are sold in a 25-piece package, making them practical for both repair stock and production use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets minimum 150,000 psi tensile strength per ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 UNF thread provides fine-pitch engagement for vibration-resistant joints\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear load distribution across the grip length\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for assemblies requiring galvanic neutrality or subsequent coating\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package for bench stock or production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.2.1 inch-series hex head cap screw for any application calling for a 3\/4-16 UNF Grade 8 fastener with partial threading and a 3-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson following the applicable torque specifications for Grade 8, 3\/4-16 UNF fasteners as defined by the equipment manufacturer or a recognized fastener standard. Always use a calibrated torque wrench and apply the correct grade of fastener lubricant or thread compound if specified by the joint design. Inspect mating threaded holes or nuts for compatible Grade 8 or higher rating before installation. Never substitute a lower-grade fastener in a joint designed for Grade 8 hardware.\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\u003eFull or Partial Threading\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 Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\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\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: C703517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696887333170,"sku":"C703517","price":81.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0071c124e092a9423748ac955b43b26a.jpg?v=1788347299","url":"https:\/\/voomisupply.com\/products\/value-collection-c703517-hex-head-cap-screw-3-4-16-x-3-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
