Manufactured from Grade L9 steel, this screw delivers high tensile strength suited to demanding bolted joints. The zinc yellow dichromate finish provides corrosion resistance while making the fastener easy to identify in the field. Thread size is 1-8 UNC with a length under head of 4-1\/2 inches, conforming to inch measurement standards. Machinists, millwrights, and maintenance technicians install this type of fastener in structural and machine-frame applications where a precise grip length and partial threading are required.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited to general industrial, manufacturing, and maintenance applications where UNC coarse-thread fasteners are specified. Partial threading allows the unthreaded shank to span joint interfaces, keeping mating surfaces in alignment under load. The hex drive accepts a 1-1\/2 inch hex key or wrench. It is appropriate for use in both original equipment assembly and field repair situations where Grade L9 strength requirements must be met.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade L9 steel construction for high tensile strength in demanding bolted connections\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and visual identification\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports precise grip length and joint alignment\u003c\/li\u003e\n  \u003cli\u003eUNC (Unified National Coarse) thread standard, 1-8 thread size\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch hex drive compatible with standard hex wrenches and impact tools\u003c\/li\u003e\n  \u003cli\u003eLength under head of 4-1\/2 inches for use in deep-reach fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for industrial assemblies specifying a 1-8 UNC partially threaded hex head cap screw in Grade L9 steel with a 4-1\/2 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist, millwright, or maintenance technician familiar with high-strength fastener procedures. Always verify that the mating threaded component and joint material are rated to accept Grade L9 fastener loads before installation. Ensure the fastening area is clean and free of debris before seating the screw. Follow applicable industry torque specifications for Grade L9 fasteners of this thread size when using a calibrated torque wrench.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4-1\/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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1-1\/2 inches\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: 0.1 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: 440730BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692738609458,"sku":"440730BR","price":19.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85a7ce924c5a4200414d9f389b1bb7df.jpg?v=1788302008","url":"https:\/\/voomisupply.com\/products\/value-collection-440730br-hex-head-cap-screw-grade-l9","provider":"Voomi Supply","version":"1.0","type":"link"}
