The insert features a 3\/8-16 internal thread and a 1\/2-13 external thread, both in UNC form, with an overall length of 0.5 inches. Manufactured from 303 stainless steel with a passivated finish, it meets NAS 1394 standards. Installation drives locking keys into the parent material to prevent rotation and pullout, making it a reliable choice for high-vibration and high-load threaded assemblies in aerospace, defense, and industrial applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for applications where a smaller installation footprint is needed than a standard-wall insert allows. The thin wall design reduces the required hole diameter in the parent material, making it useful in tight-clearance components and thin-section parts. It is commonly installed in aluminum, steel, and other machinable materials across aerospace, military, and precision industrial assemblies. Licensed machinists and assembly technicians working to NAS specifications will recognize the fit and form of this insert type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 internal thread with 2B class of fit for standard fastener engagement\u003c\/li\u003e\n\u003cli\u003e1\/2-13 external thread with 2A class of fit for precise installation hole requirements\u003c\/li\u003e\n\u003cli\u003eThin wall keylocking design minimizes required parent material envelope\u003c\/li\u003e\n\u003cli\u003e303 stainless steel construction with passivated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets NAS 1394 standard for keylocking threaded inserts\u003c\/li\u003e\n\u003cli\u003eOverall length of 0.5 inches suits shallow-depth thread installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thin wall keylocking insert for use in parent materials machined to accept a 1\/2-13 external thread installation hole per NAS 1394 requirements.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly sized and toleranced installation hole tapped to 1\/2-13 UNC in the parent material. A keylocking insert installation tool is used to drive the locking keys into the parent material after the insert is threaded in to the required depth. Power down and de-energize any assembly before performing threaded insert work on electrical or mechanical components. Follow NAS 1394 and applicable engineering specifications for key engagement depth and inspection criteria.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Thin Wall Keylocking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Passivated\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\u003eStandard\u003c\/strong\u003e: NAS 1394\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 215-066324\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52080910926130,"sku":"215-066324","price":24.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/daa3728e5144cde1b9883d44608bd13d_df704402-9bfa-482e-9909-dc1fcc76117a.jpg?v=1790055858","url":"https:\/\/voomisupply.com\/products\/jergens-215-066324-keylocking-thread-insert-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
