Manufactured from Grade L9 alloy steel, this fastener offers superior tensile strength compared to standard Grade 5 or Grade 8 fasteners, making it well-suited for demanding bolted joints subject to high loads or vibration. The 5\/16-24 UNF thread form provides fine-thread engagement for applications where precise clamping force and resistance to loosening are required. A zinc yellow dichromate finish provides corrosion resistance and a distinctive yellow identification coating. Licensed mechanics, maintenance technicians, and industrial assemblers are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial machinery, automotive assemblies, heavy equipment, and precision mechanical systems where a fine-thread, high-strength fastener is specified. The 5\/16-24 thread size and 2-inch length under head make it appropriate for medium-depth bolted connections in steel components. Partial threading leaves a smooth shank section near the head, which is standard in applications where shear strength or close-tolerance fit in the grip zone is needed. The 1\/2-inch hex key size (across flats) accepts standard hex wrenches and sockets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade L9 alloy steel construction for high tensile strength beyond standard Grade 8 specifications\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF fine-thread form for precise clamping force and vibration resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides full grip-zone shear capacity\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance and easy grade identification\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex across flats accepts common sockets and open-end wrenches\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head suits medium-depth structural and mechanical connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or replacement fastener for bolted assemblies specifying a 5\/16-24 UNF partially threaded hex head cap screw in Grade L9 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanics, millwrights, or maintenance technicians using a 1\/2-inch hex socket or open-end wrench. Ensure mating threads are clean and free of debris before installation. Follow the torque specifications provided by the equipment or assembly manufacturer for Grade L9 fasteners of this size. Do not substitute this fastener in applications specifying a different grade, thread standard, or thread engagement length without engineering review.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2 inches\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: L9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0053 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 440144PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709508911410,"sku":"440144PR","price":592.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/415654cc2bd36f6d4b839fcef82e73dd_0b477cce-a191-46a3-8588-cd83bbe15114.jpg?v=1788457322","url":"https:\/\/voomisupply.com\/products\/value-collection-440144pr-hex-cap-screw-5-16-24-x-2-in-grade-l9","provider":"Voomi Supply","version":"1.0","type":"link"}
