It features an M12 x 1.75 internal thread and an M18 x 1.5 external thread, with an overall length of 18 mm (approximately 0.709 inches). Manufactured from carbon steel, this insert is driven into a pre-tapped host bore and locked in place with keys that embed into the parent material, preventing rotation or pullout under load. It is installed by machinists, tool-and-die technicians, and maintenance professionals working on metric fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for production and repair applications where a metric coarse internal thread must be established or restored in a parent material. The keylocking design is particularly useful in high-vibration or high-load environments where standard thread repair inserts may not provide adequate retention. Typical applications include machinery frames, tooling fixtures, and structural assemblies requiring a reliable M12 threaded connection within a larger M18 tapped hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003eM12 x 1.75 internal thread accepts standard metric coarse fasteners\u003c\/li\u003e\n \u003cli\u003eM18 x 1.5 external thread installs into a matching tapped host bore\u003c\/li\u003e\n \u003cli\u003e18 mm overall length for adequate thread engagement depth\u003c\/li\u003e\n \u003cli\u003eKeylocking design mechanically locks insert against rotation and axial pullout\u003c\/li\u003e\n \u003cli\u003eCarbon steel construction for durability in ferrous and non-ferrous host materials\u003c\/li\u003e\n \u003cli\u003eHeavy-duty series rated for high-load and high-vibration service conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-use keylocking threaded insert for metric thread repair and reinforcement applications requiring an M12 x 1.75 internal thread within an M18 x 1.5 tapped bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly tapped M18 x 1.5 host bore prepared to the manufacturer's specified depth. A dedicated keylocking insert installation tool is used to drive the locking keys into the parent material after the insert is threaded into place. Power down and de-energize any equipment before performing thread repair on machine components. Follow applicable shop safety procedures and consult the insert manufacturer's installation guidelines for correct key-driving technique.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eInternal Thread\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eExternal Thread\u003c\/strong\u003e: M18 x 1.5\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 18 mm (0.709 inches)\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: Heavy-Duty Keylocking\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 215-065969\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":68306243551538,"sku":"215-065969","price":34.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/372645522a34bd793a6ad49ea7f19952.jpg?v=1793753170","url":"https:\/\/voomisupply.com\/products\/jergens-215-065969-keylocking-thread-insert-m12x1-75-m18x1-5","provider":"Voomi Supply","version":"1.0","type":"link"}
