The insert measures 0.43 inches overall length and accepts a 5\/16-24 UNF internal thread while threading into a 7\/16-14 UNF external hole. Manufactured from C1215 carbon steel with a zinc phosphate coating, this insert is built for use in metalworking, aerospace, and industrial assembly applications where thread pullout resistance and a slim wall profile are required. Installation is performed by qualified machinists or mechanical assembly technicians.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications where a smaller internal thread size must be placed within a parent material bore that calls for a larger external thread. The thin wall design preserves more parent material compared to standard keylocking inserts, making it appropriate for components with limited wall thickness. Common installation scenarios include aerospace structural assemblies, precision machined housings, and industrial equipment repairs requiring permanent thread reinforcement. The insert meets NAS 1394 standards and carries a 2B internal thread class of fit and 2A external thread class of fit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-24 UNF internal thread with 2B class of fit for standard fastener engagement\u003c\/li\u003e\n  \u003cli\u003e7\/16-14 UNF external thread with 2A class of fit for secure installation into parent bore\u003c\/li\u003e\n  \u003cli\u003eThin wall keylocking design preserves parent material around the bore\u003c\/li\u003e\n  \u003cli\u003eC1215 carbon steel construction with zinc phosphate coating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e0.43 inches overall length for compact, space-efficient installations\u003c\/li\u003e\n  \u003cli\u003eManufactured to NAS 1394 standards for aerospace and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread repair and reinforcement insert for metalworking and industrial assembly applications requiring a 5\/16-24 UNF internal thread in a 7\/16-14 UNF tapped hole.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or mechanical assembly technician using a dedicated keylocking insert installation tool. The parent material bore must be tapped to 7\/16-14 UNF specifications before the insert is driven in. Power down and de-energize any equipment before servicing threaded connections on live assemblies. Follow applicable industry and facility standards for thread insert installation procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 7\/16-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eOverall Length\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Thin Wall 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\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: 215-066123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52089270894898,"sku":"215-066123","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c29e32ce000816ab887a7f3e71e5a973.jpg?v=1790061660","url":"https:\/\/voomisupply.com\/products\/jergens-215-066123-keylocking-thread-insert-5-16-24","provider":"Voomi Supply","version":"1.0","type":"link"}
