Manufactured from Grade 8 steel, this fastener delivers high tensile strength suited for demanding mechanical and structural assemblies. The zinc yellow dichromate finish provides corrosion resistance and is visually distinct for easy identification in Grade 8 applications. It conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for engineers, machinists, and maintenance professionals working to specification.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used across a wide range of industrial, mechanical, and equipment assembly applications where high-strength fasteners are required. Grade 8 fasteners are commonly specified for heavy equipment, automotive, agricultural machinery, and structural connections that see significant load or vibration. The fully threaded design provides maximum thread engagement throughout the grip length, making it well suited for thinner material stacks or applications where full clamping force is needed from head to end.\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 strength\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e9\/16-12 UNC thread form per standard Unified National Coarse specification\u003c\/li\u003e\n  \u003cli\u003e1 inch length measured under head per ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion resistance and Grade 8 identification\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or general-use hex head cap screw for any application requiring a 9\/16-12 UNC fully threaded Grade 8 fastener with a 1 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical and maintenance trades using standard hex wrenches or sockets sized for a 9\/16-12 hex head cap screw. Ensure mating threaded holes or nuts are clean and free of debris before installation. Grade 8 fasteners should be torqued to the value specified by the equipment manufacturer or applicable engineering standard for the joint design. Do not mix Grade 8 fasteners with lower-grade nuts or tapped holes that are not rated for the corresponding load.\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\u003eDimensional Standard\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\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: D39129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697635655986,"sku":"D39129","price":47.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59c698d03b6bb93a164c6cc6b7e5dc76.jpg?v=1788353643","url":"https:\/\/voomisupply.com\/products\/value-collection-d39129-hex-head-cap-screw-9-16-12-x-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
