The insert accepts an M12 x 1.75 internal thread and uses a 3\/4-10 external thread to lock into the parent material. Manufactured from C12L14 carbon steel with a smooth, rolled finish, this insert measures 0.656 inches in overall length. It is installed by licensed trade professionals and maintenance technicians working with metric fastening applications in ferrous and non-ferrous base materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for applications requiring a metric coarse or metric fine internal thread where the base material thread condition is compromised, undersized, or requires reinforcement. The 3\/4-10 external thread engages a standard-tapped hole, while the M12 x 1.75 internal thread accepts the mating fastener. Typical install scenarios include industrial equipment repair, HVAC equipment frames, pump housings, and machinery where metric fastener engagement must be restored or reinforced.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12 x 1.75 internal thread with a 2B class of fit for standard metric coarse and metric fine applications\u003c\/li\u003e\n\u003cli\u003e3\/4-10 external thread with a 2A class of fit locks into a standard-tapped parent hole\u003c\/li\u003e\n\u003cli\u003eStandard wall design accommodates typical wall thickness requirements without oversized tapping\u003c\/li\u003e\n\u003cli\u003eC12L14 carbon steel construction provides reliable thread strength in ferrous base materials\u003c\/li\u003e\n\u003cli\u003eSmooth, rolled finish on the external thread aids installation and thread engagement\u003c\/li\u003e\n\u003cli\u003eOverall length of 0.656 inches suits compact fastener joint applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread repair and locking insert for applications requiring an M12 x 1.75 internal thread installed via a standard 3\/4-10 tapped hole in carbon steel or compatible base materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist, maintenance technician, or journeyman tradesperson using a standard tap sized for 3\/4-10 threads and the appropriate E-Z LOK installation tool. The workpiece should be fully de-energized or depressurized before insert installation when working on energized or pressurized equipment. Do not exceed the recommended torque range for the parent material, and do not install in materials with insufficient wall thickness to support the external thread engagement. Follow applicable fastener and equipment service codes for the specific application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Thread Size\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Thread Size\u003c\/strong\u003e: 3\/4-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse, Metric Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Standard Wall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.656 inches\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: C12L14\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\u003eCoating\/Finish\u003c\/strong\u003e: Smooth, Rolled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Tap Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.036 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: E-Z LOK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 650-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"E-Z LOK","offers":[{"title":"Default Title","offer_id":67905991934258,"sku":"650-12","price":21.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dd40a2d7819c6faddf17824c600df5e.jpg?v=1791161792","url":"https:\/\/voomisupply.com\/products\/e-z-lok-650-12-thread-locking-insert-m12-x-1-75-3-4-10","provider":"Voomi Supply","version":"1.0","type":"link"}
