Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers high tensile strength and corrosion resistance suited for heavy-duty mechanical and structural assemblies. The partial threading configuration follows ASME B18.2.1 and SAE J429 standards, making it a recognized choice for critical bolted joints where grip length and clamping load matter. Machinists, millwrights, and maintenance technicians working in industrial, agricultural, and heavy equipment applications commonly specify Grade 8 hardware for these load-bearing connections.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in applications requiring high-strength inch-series fasteners with a coarse UNC thread form. The zinc yellow dichromate finish provides a baseline level of corrosion protection suitable for indoor mechanical assemblies, general industrial machinery, and equipment where the fastener may see moderate environmental exposure. It is sold individually, with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003e9\/16-12 UNC coarse thread form for broad compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a grip section for precise clamping in bolted joints\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance and visual identification of Grade 8 rating\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 and SAE J429 standards for dimensional and mechanical compliance\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head accommodates thicker stack-ups and structural assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series replacement or new-installation hex head cap screw for use with any 9\/16-12 UNC tapped hole or matching nut in heavy-duty mechanical and structural assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a standard hex wrench or socket set. Always confirm the mating thread is 9\/16-12 UNC before installation and inspect threads for damage or contamination. Follow torque specifications for Grade 8 fasteners as published by the equipment manufacturer or applicable engineering standards. Reuse of fasteners in critical joints should be evaluated against the original design requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: D39143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716036559154,"sku":"D39143","price":25.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28f09c51ceb250c5dcd76c5a72540b89.jpg?v=1788521373","url":"https:\/\/voomisupply.com\/products\/value-collection-d39143-hex-cap-screw-9-16-12x5-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
