The insert features a 1-8 UNC internal thread and a 1-3\/8-12 external thread, with an overall length of 1.375 inches. Manufactured from C1215 carbon steel with a zinc phosphate coating for corrosion resistance, this insert meets NAS 1394 standards. Installation is performed by licensed maintenance technicians, industrial mechanics, or MRO professionals working on heavy equipment, tooling, or structural assemblies.\u003c\/p\u003e\n\u003cp\u003eThis keylocking insert is suited for applications requiring a durable threaded hole in metal assemblies where thread stripping is a concern. The heavy-duty design handles high-load fastening situations in industrial, aerospace, and defense manufacturing environments. It is installed into a pre-drilled and tapped hole in the parent material, after which keys are driven into place to lock the insert and prevent rotation under torque or vibration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy-duty keylocking design resists rotation under high torque and vibration loads\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC internal thread with Class 2B fit for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-12 external thread with Class 2A fit for secure installation in parent material\u003c\/li\u003e\n  \u003cli\u003eC1215 carbon steel construction with zinc phosphate coating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 1394 standards for keylocking thread inserts\u003c\/li\u003e\n  \u003cli\u003e1.375-inch overall length suits deeper thread engagement requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty keylocking thread insert conforming to NAS 1394, suitable for installation into parent materials tapped to accept a 1-3\/8-12 external thread for applications requiring a 1-8 UNC internal thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified industrial mechanics or maintenance professionals using the appropriate keylocking insert installation tool. The parent material must be drilled and tapped to the correct external thread specification before insert installation. Power down or de-energize any associated equipment before beginning work. Keys must be driven flush or below the parent material surface after the insert is seated to prevent loosening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1-3\/8-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Class of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Class of Fit\u003c\/strong\u003e: 2A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Heavy-Duty Keylocking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1215\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Zinc Phosphate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 1394\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: JERGENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 215-065911\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52088815812914,"sku":"215-065911","price":61.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9330e02f9fb90e17486183ddc80d3b7.jpg?v=1790061342","url":"https:\/\/voomisupply.com\/products\/jergens-215-065911-keylocking-thread-insert-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
