Thread inserts: how to restore damaged threads to better than new condition.
If your threads are not completely destroyed, you can try "chasing" the threads with a thread chasing tap. This may realign the threads so that the bolt can be threaded in place. A thread chaser is essentially a slightly undersized tap that will clean threads without removing any metal.
When thread damage is too severe to be saved with a thread chaser, you can completely restore the threads with new coil-type thread inserts. They will provide a completely new threaded hole (with strong steel threads) that accepts the original size bolt. They are installed by drilling the damaged thread hole slightly oversize, tapping it with a larger tap, and screwing in the new thread insert coil.

Why you should install thread repair inserts:
Virtually everything on your vehicle is held together with nuts and bolts. Whenever you unbolt something and put it back together, you stand a chance of stripping or cross-threading the threads.
Most threads can be repaired with thread inserts that actually make the threads stronger than those found in aluminum or cast iron parts. If you don’t correctly repair damaged threads, you will not be able to properly tighten the fastener, and the connection will fail over time.
