BaerFix® thread inserts with three cutting holes are self-tapping guarantee a permanent fixed thread connection in your workpiece and are extremely easy to use. Simply screw them into the hole - you cut the holding thread yourself.
If your spark plug thread or glow plug thread is worn or torn out, a stable connection with the spark plug or glow plug is no longer possible. This is where the self-tapping BaerFix® thread insert comes into play. With our self-tapping thread inserts you can repair your broken internal thread or strengthen the existing thread. If the thread in your cylinder head is damaged, this does not have to be a scrap. Simply insert a threaded bush with the same internal thread into the component so that your thread is not only repaired, but can also be loaded with higher pull-out strength at the same time and also becomes more wear-resistant. The thread inserts are designed so that the sealing ring of the spark plug protrudes beyond the thread insert.
The BaerFix® self-tapping thread inserts with tapping holes are ideal when you want to create a strong connection for light and difficult-to-machine materials. These inserts can take more force, which is also distributed over three cutting holes.
