Heavy Duty Threaded Inserts Manufacturer

Heavy duty key locking threaded inserts are an effective tool to efficiently repair any damaged, worn or stripped-out threads that may be a risk to the integrity of your machine or other application. In addition, by choosing these inserts, you can regain confidence in the strength of these screw connections by installing a freshly threaded insert.

Heavy duty inserts are generally used in industrial applications where loose connections can be hazardous to anyone. They are designed with a thick thread wall and are even effective where the mating stud or bolt must be removed regularly.

The key locking element of these inserts makes them a great choice when working with softer metals such as magnesium and aluminium. This is because the key locking will provide a substantially stronger connection between the thread and the material, and it can even work with plastic.

Key locking threaded inserts are easy to install and can significantly improve any connection they are used for. At Metrol, we are confident we have everything you need for your next project.
