Not to beat this thing up but, How thick does the metal have to be to have 2 threads fully engaged and not have to use nuts on the back side.
I would think a meter can is not thick enough to have 2 full threads engaged where you could use a self tap or self drilling screw without nuts on the backside.

You are correct, you would need to use a tap and a machine screw.

Well, a 6-32 or 8-32, with 32 threads per inch, would require the metal to be at least 1/16".
 
Here is the definition. The proposal was from the Telecom association. Its a great rule.
Intersystem Bonding Termination. A device that provides a means for connecting communications system(s) grounding conductor(s) and bonding conductor(s) at the service equipment or at the disconnecting means for buildings or structures supplied by a feeder or branch circuit.
 
I have not heard of any inspector requiring it, but is exactly what I did when I built my last home. The bare #4 runs out the bottom of the meter can, is welded to the ground bar, at the opposite end of the bar is another #4 welded and goes straight down to the GES.

My CATV block mounts directly on the ground bar, and The Telco NIU is mounted right next to the ground bar with a copper strap welded to the ground bar and terminated to the NIU ground stud.
