The insert accepts a 7\/16-14 UNC internal thread and installs via a 5\/8-11 UNC external thread, with an overall length of 0.620 inches. Finished in zinc phosphate for corrosion resistance, this carbon steel insert conforms to NAS 1394 standards and meets material grade C1215. It is installed by machinists, maintenance technicians, and MRO professionals working on threaded repair and reinforcement applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications where a smaller internal thread must be anchored into a larger tapped hole, including thread repair in worn or stripped bores and original equipment installations requiring high pull-out resistance. The heavy-duty keylocking design provides superior resistance to rotation and axial displacement compared to standard coil-type inserts, making it appropriate for high-vibration and high-load environments in industrial and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy-duty keylocking design resists rotation and axial pullout under high load and vibration\u003c\/li\u003e\n  \u003cli\u003e7\/16-14 UNC internal thread with Class 2B fit for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC external thread with Class 2A fit for precise installation into parent bore\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction at material grade C1215 for strength and machinability\u003c\/li\u003e\n  \u003cli\u003eZinc phosphate coating provides corrosion resistance and improved surface adhesion\u003c\/li\u003e\n  \u003cli\u003eConforms to NAS 1394 standard for thread locking insert performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-installation heavy-duty keylocking thread insert for UNC-threaded applications requiring a 5\/8-11 external installation thread and a 7\/16-14 internal thread, conforming to NAS 1394.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified maintenance technicians using the appropriate keylocking insert installation tool for the 5\/8-11 external thread size. The parent material must be properly tapped to the correct minor diameter before insert installation. Ensure the workpiece is securely fixtured and de-energized or de-pressurized as applicable to the assembly before beginning work. Keys must be driven in after insert installation to lock it against rotation per standard keylocking insert procedure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 7\/16-14 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 5\/8-11 UNC\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: 0.620 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\u003eStandard\u003c\/strong\u003e: NAS 1394\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: 215-065905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51972301062450,"sku":"215-065905","price":15.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ea2c4cffc430ca29804bd57750f5e96.jpg?v=1789965793","url":"https:\/\/voomisupply.com\/products\/jergens-215-065905-thread-locking-insert-7-16-14-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
