With the BaerFix® spark plug thread repair set, damaged MF 14 x 1.25 threads can be repaired quickly and easily.

This set contains all the tools you need to achieve a permanent and strong anchorage in various materials. The BaerFix® thread repair set is ideal for materials such as aluminium, light metals, non-ferrous metals, brass, bronze, cast iron, plastics, laminates and hardwood. Please note that the set is only suitable for materials with a tensile strength up to approx. 450 N/mm².

BaerFix® thread inserts are self-tapping, guarantee a permanently tight threaded connection in your workpiece and are extremely easy to use. Simply screw into the hole - the inserts cut the holding thread themselves. Once your thread is worn or torn out, a stable connection between the materials is no longer possible. This is where BaerFix® thread insert comes to the rescue. With our self-tapping thread inserts you can repair or strengthen damaged internal thread. Damaged threads in your components do not have to be rejects. Simply insert a threaded insert with the same internal thread into the component and your thread will not only be repaired, it will also be more pull-out resistant and wear resistant. The pull-out strength is higher than a class 8.8 screw.

To assist with the repair, in addition to the thread inserts, the set includes a core drill bit, a taper countersink and an assembly tool. Use the core drill bit to prepare the core hole and the installation tool to insert the self-tapping thread insert.
