Repair Damaged Or Worn Threads

WARNING: This page is about a different variant/trim than selected.
CAUTION: Be sure that the tapped holes maintain the original center line.

Damaged or worn threads can be repaired. Essentially, this repair consists of:

  1. Drilling out worn or damaged threads.
  2. Tapping the hole with a special Heli-Coil Tap, or equivalent.
  3. Installing an insert into the tapped hole to bring the hole back to its original thread size.
