Sized at 9\/16-12 UNC with a 1-inch length under head, this fastener is manufactured from Grade L9 steel and finished with a zinc yellow dichromate coating that provides corrosion resistance in demanding service environments. The hex drive measures 13\/16 inch across flats, accepting a standard hex socket or wrench. Grade L9 denotes an alloy steel fastener with elevated tensile strength, making it suitable for critical clamping loads where standard Grade 5 or Grade 8 hardware may be insufficient. Licensed trades and industrial maintenance professionals typically specify this grade for heavy equipment, hydraulic connections, and structural assemblies.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for general industrial, mechanical, and structural fastening applications where a UNC thread form is required. The fully threaded body provides consistent thread engagement along the full length under head, which is advantageous in thin-material joints or wherever maximum thread contact is needed. Typical use cases include equipment assembly, maintenance and repair of heavy machinery, and fabrication work requiring a high-strength inch-series fastener. The zinc yellow dichromate finish offers added protection in environments with moderate moisture or chemical exposure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade L9 steel construction for high tensile strength in critical fastening applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded 9\/16-12 UNC body maximizes thread engagement for the full 1-inch length under head\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance in moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003e13\/16-inch hex key size accepts standard sockets and open-end wrenches\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with UNC thread standard for compatibility with common inch-series hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use fastener for applications requiring a 9\/16-12 UNC fully threaded hex head cap screw in Grade L9 steel with a zinc yellow dichromate finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician familiar with high-strength fastener procedures. De-energize, depressurize, or otherwise make safe any equipment before replacing fasteners in load-bearing or pressurized assemblies. Use a calibrated torque wrench and follow the equipment manufacturer's torque specifications for Grade L9 hardware — do not substitute generic torque tables from lower-grade fastener specifications. Inspect mating threads for damage or contamination before installation, and replace any hardware that shows signs of galling, corrosion, or deformation.\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: 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: 13\/16 inch\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: 0.5 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: 440422PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693913833778,"sku":"440422PR","price":771.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72d00f94681f54decffaf63162506079.jpg?v=1788318978","url":"https:\/\/voomisupply.com\/products\/value-collection-440422pr-hex-head-cap-screw-9-16-x-1-in-l9","provider":"Voomi Supply","version":"1.0","type":"link"}
