The insert accepts an M20 x 1.5 internal thread and installs via an M30 x 2 external thread, with an overall length of 30 mm. It is manufactured from C1215 carbon steel with a zinc phosphate coating for corrosion resistance. The internal thread class of fit is 6H and the external thread class of fit is 6G, conforming to NAS 1394. Licensed JERGENS-system installers and maintenance machinists typically install this insert in production or repair applications where a high-strength threaded connection is required in a drilled and tapped bore.\u003c\/p\u003e\u003cp\u003eThis insert is suited for industrial maintenance, OEM production, and repair applications requiring a metric fine internal thread. The heavy-duty keylocking design uses keys that are driven into the parent material to lock the insert in place and prevent rotation under high torque and dynamic loading. It is appropriate for use in metal parent materials across a range of industries including aerospace, defense, and general manufacturing where metric fine thread standards apply.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM20 x 1.5 internal thread with 6H class of fit for precise metric fine thread engagement\u003c\/li\u003e\n\u003cli\u003eM30 x 2 external thread with 6G class of fit for controlled installation into parent material bore\u003c\/li\u003e\n\u003cli\u003e30 mm overall length for deep thread engagement in heavy-duty applications\u003c\/li\u003e\n\u003cli\u003eC1215 carbon steel construction with zinc phosphate coating for durability and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eHeavy-duty keylocking design prevents rotation and pullout under high-load conditions\u003c\/li\u003e\n\u003cli\u003eConforms to NAS 1394 standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for installation in any parent material bored and tapped to accept an M30 x 2 external thread, providing a permanent M20 x 1.5 internal thread.

The parent material bore must be drilled and tapped to the correct M30 x 2 specification before insert installation. After seating the insert, drive the locking keys flush with or below the surface of the parent material to secure the insert against rotation. Always follow NAS 1394 and the applicable shop procedure for insert installation depth and key driving sequence.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: M20 x 1.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: M30 x 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 30 mm\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Zinc Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Heavy-Duty Keylocking\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: 0.1 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: 215-066173\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52088347066674,"sku":"215-066173","price":425.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca24e32de15ea09ebbb3f91d3bffa4f6_222db885-a21a-4c87-829b-e2c558a8ad74.jpg?v=1790061014","url":"https:\/\/voomisupply.com\/products\/jergens-215-066173-keylocking-thread-insert-m20x1-5-m30x2","provider":"Voomi Supply","version":"1.0","type":"link"}
