Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade alternatives. The 7\/16-20 UNF thread form provides fine-thread engagement for applications requiring precise torque control and vibration resistance. The 3-inch length under head suits medium-depth through-bolt and threaded-insert installations. This screw meets ASME B18.2.1 dimensional standards, making it a reliable choice for precision assemblies where dimensional conformance is required.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for use in mechanical and industrial applications where high-strength steel fasteners are specified. The fine UNF thread pattern makes it appropriate for use in metal-to-metal assemblies, machinery frames, brackets, and equipment where vibration resistance is a priority. It is commonly specified by maintenance technicians, millwrights, and fabricators working on manufacturing equipment, transportation components, and structural hardware requiring Grade 8 rated fasteners.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n\u003cli\u003e7\/16-20 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n\u003cli\u003e3-inch length under head accommodates medium-depth fastening applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank allows for clamping force across unthreaded grip length\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.2.1 dimensional standards for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimensional Grade 8 hex head cap screw conforming to ASME B18.2.1, suitable for use in any application calling for a 7\/16-20 UNF partially threaded fastener in that thread and length specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by maintenance technicians, millwrights, or fabricators using standard hex wrenches or sockets sized for the 7\/16-20 hex head. Always clean and inspect the mating threaded hole or nut before installation to ensure thread integrity. Apply appropriate thread lubricant or thread-locking compound per the equipment manufacturer's specification. Grade 8 fasteners require a calibrated torque wrench to achieve correct clamp load without risk of fastener failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\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\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 Yellow Dichromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 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: MP39387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695064809778,"sku":"MP39387","price":23.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6415f3edb9892ef82115631e4b6756.jpg?v=1788330994","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39387-hex-cap-screw-7-16-20-x-3-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
