It accepts an M16 x 2 internal thread and installs into a prepared M22 x 1.5 tapped hole, with an overall length of 22 mm. Made from C1215 carbon steel with a zinc phosphate coating, this insert resists torque-out and pull-out forces that standard threaded inserts cannot handle. It meets NAS 1394 standards and carries a 6H internal thread class of fit and a 6G external thread class of fit. Machinists, tool and die technicians, and maintenance mechanics install these in production fixtures, heavy equipment, and structural assemblies where thread integrity is critical.\u003c\/p\u003e\n\u003cp\u003eThis keylocking insert is intended for use in metallic base materials where the parent thread has been damaged, upgraded for higher load capacity, or engineered from the start for removable fastener access. The metric coarse thread standard makes it suitable for European-spec machinery, import equipment, and any application calling for M16 x 2 threaded connections. It is commonly installed in steel and cast iron housings in industrial, aerospace-adjacent, and heavy manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM16 x 2 internal thread with 6H class of fit for precise fastener engagement\u003c\/li\u003e\n  \u003cli\u003eM22 x 1.5 external thread with 6G class of fit for accurate installation bore fit\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty keylocking design resists rotation and axial pull-out under high loads\u003c\/li\u003e\n  \u003cli\u003eC1215 carbon steel construction with zinc phosphate coating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 1394 standard for keylocking threaded inserts\u003c\/li\u003e\n  \u003cli\u003e22 mm overall length suits standard-depth tapped bores in heavy-duty applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for installation into metallic parent materials tapped to M22 x 1.5 to provide a permanent M16 x 2 internal thread. Verify parent material hardness and bore depth against NAS 1394 installation requirements before use.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly tapped M22 x 1.5 bore and a keylocking insert installation tool to drive and key the insert into the parent material. Always power down and de-energize any equipment before performing thread repair or insert installation on live machinery. Keys must be driven flush or below flush after installation to lock the insert against rotation. Follow NAS 1394 guidelines for bore preparation, insert seating depth, and key-driving 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: M16 x 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: M22 x 1.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Heavy-Duty Keylocking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 22 mm\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\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 215-065971\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51972093378866,"sku":"215-065971","price":310.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca24e32de15ea09ebbb3f91d3bffa4f6_e425778c-bdcd-400e-a63a-dd5196781d3d.jpg?v=1789962572","url":"https:\/\/voomisupply.com\/products\/jergens-215-065971-keylocking-thread-insert-m16x2-m22x1-5","provider":"Voomi Supply","version":"1.0","type":"link"}
