How can you repair a stripped bolt hole?

To repair a stripped bolt hole, you can use a thread repair insert, such as a Helicoil, which involves drilling out the damaged threads, tapping a new thread, and installing the insert. Alternatively, you can fill the hole with a high-strength epoxy or metal-filled adhesive, then drill and tap new threads once cured. Another option is to use a slightly larger bolt and re-tap the hole to fit the new size. Always ensure that the repair method chosen is suitable for the material and application.
