The insert features an M8 x 1.25 internal thread and an M12 x 1.25 external thread, with an overall length of 12 mm. It is manufactured from C1215 carbon steel with a zinc phosphate coating for corrosion resistance. These inserts are installed by machining professionals and maintenance technicians to restore or create load-bearing threads in components subject to vibration or frequent fastener cycling. The keylocking design mechanically locks the insert into the parent material, preventing rotation under load.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for use in metalworking, industrial maintenance, and OEM assembly applications where thin wall clearances prevent the use of standard-wall inserts. The metric coarse thread standard and 12 mm overall length make it appropriate for mid-thickness bosses and flanges in steel, aluminum, and cast components. It meets NAS 1394 standards, making it applicable in aerospace, defense, and precision manufacturing environments where fastener thread integrity is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM8 x 1.25 internal thread with 6H class of fit for standard metric fastener engagement\u003c\/li\u003e\n  \u003cli\u003eM12 x 1.25 external thread with 6G class of fit for precise parent-hole installation\u003c\/li\u003e\n  \u003cli\u003eThin wall design allows installation in confined boss geometries with limited outer diameter clearance\u003c\/li\u003e\n  \u003cli\u003eC1215 carbon steel construction with zinc phosphate coating for corrosion and wear resistance\u003c\/li\u003e\n  \u003cli\u003eKeylocking mechanism prevents insert rotation under vibration and dynamic loading\u003c\/li\u003e\n  \u003cli\u003eMeets 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 an OEM-style replacement and standard-installation thread locking insert for metric coarse threaded applications requiring an M8 x 1.25 internal thread in an M12 x 1.25 parent bore, 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 a dedicated keylocking insert installation tool to drive and stake the locking keys into the parent material. The parent hole must be drilled and tapped to the correct M12 x 1.25 specification before insert installation. Always de-energize and lock out any machinery before performing thread repair or insert installation work. Follow NAS 1394 installation procedures for proper key engagement and flush seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: M8 x 1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: M12 x 1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Thread Class of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Class of Fit\u003c\/strong\u003e: 6G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12 mm\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  \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: 215-065953\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":67647703613746,"sku":"215-065953","price":90.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca24e32de15ea09ebbb3f91d3bffa4f6_3ad66963-e7c8-4ab0-8411-0ffef322f632.jpg?v=1790459905","url":"https:\/\/voomisupply.com\/products\/jergens-215-065953-thread-locking-insert-m8x1-25-thin-wall","provider":"Voomi Supply","version":"1.0","type":"link"}
