One of my favorite tools - Quickly and easily put a threaded hole in thin metal and/or repair a stripped out hole in an electrical box (see warning below).

- Compression inserts (threaded)
- Compression tool
- Drill bit (per insert size) / drill

WARNING: Never drill into an electrical box with live wires. Protect wires. Always use appropriate safety equipment and procedures. If you don't know, learn or don't do it!
