This is a common occurance. there are two approaches to fixing it:
1. Drill out the stripped hole and tap it larger. Install a special repair stud that has a larger diameter on the lower end. MMI sells a kit
2. Drill out the stripped hole and tap it larger. Install a threaded insert (not a helicoil, they can leak), and install a new standard stud.
