Manufactured from Grade L9 alloy steel, this fastener delivers superior tensile strength compared to standard Grade 5 or Grade 8 hardware. The zinc yellow dichromate finish provides corrosion resistance suitable for general industrial environments. With a 1\/2-13 UNC thread and 8-inch length under head, this screw is sized for heavy-duty bolted joints where full clamping force and precise thread engagement are critical. Installers, millwrights, and maintenance mechanics will find this fastener appropriate for demanding bolted connections.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for industrial machinery assembly, structural steel connections, heavy equipment maintenance, and fabrication work requiring high-strength inch-series fasteners. The 1\/2-13 UNC thread is one of the most common coarse-thread profiles in inch-series applications, making this screw broadly applicable across manufacturing, construction, and mechanical service environments. Partial threading allows the unthreaded shank to bear shear loads in bolted joint designs where shank fit in the hole is important.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade L9 alloy steel construction for high tensile strength in demanding fastener applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear load transfer in precision bolted joints\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread — a widely used inch-series profile for broad tooling compatibility\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion resistance in general industrial service\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex key size compatible with standard 3\/4-inch drive or open-end tooling\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head accommodates thick material stacks and long-reach clamping needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or aftermarket fastener for any application requiring a 1\/2-13 UNC partially threaded hex head cap screw in Grade L9 alloy steel with zinc yellow dichromate finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or maintenance technician following applicable torque specifications for Grade L9 hardware as defined by the fastener manufacturer or relevant engineering documentation. Always de-energize and lock out equipment before fastener replacement on live machinery. Use a properly sized 3\/4-inch wrench or socket to avoid rounding the hex drive. Do not substitute this Grade L9 fastener with lower-grade hardware in joints designed for high-strength fasteners 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: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\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\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 3\/4 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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 440374PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715063841074,"sku":"440374PR","price":783.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73fbfd2700d5f86790149c824fd16a14.jpg?v=1788509469","url":"https:\/\/voomisupply.com\/products\/value-collection-440374pr-hex-cap-screw-1-2-13-x-8-in-grade-l9","provider":"Voomi Supply","version":"1.0","type":"link"}
