Thread Restoration Tools!
What does a thread restorer tool do? Simple, it restores threads… duh! Okay, okay, there is a bit more to it. A thread restorer or thread file like #8185 - 4 Pc. Thread Restoring Kit is a tool used to fix threads on nuts or bolts that have become damaged. The damaged thread on a screw or bolt can often be fixed by running a die over it, and if a thread's damage is minimal, it may be possible to reform the threads by running a nut up and down them, though that runs the risk of the nut fusing to the threads, also known as galling.
On the other hand, Re-Conditioning or rethreading tap is designed to create new threads, whereas a chaser tap is designed to clean, re-form, and restore existing threads. If you want to clean-up existing female threads it is best to use a chaser, or follower tap instead of a common cutting tap like #8240 - 53 Pc. Master Rethreading Set. If the hole requires new threads entirely, use a rethreading tap tool like #7730 - Glow Plug Thread Repair Kit or Pro-Thread Repair Kits to restore threaded engine component holes. This can also be performed on nuts or other internal thread applications.
Pro Tip: Do not try to rethread the entire bolt, hole, or nut in one operation. Insert the rethreading tap or die and rotate a few turns, then back it off a full turn. That will dislodge the debris from the teeth of tap, ensuring the threads are properly engraved.
