Propane Copper Pipe Hangers
I would use stainless steel screws and an internal tooth lock washer just to be safer from vibration. I like to be able to easily fix stuff. If you routinely carry an electric drill, bits, and a pop rivet tool, have at it with wide head pop rivets.
Your repair habits rule the correct answer. Admittedly I carry the drill and all the other stuff as well. Just donít like to drill out rivets over my face while lying under the AS.
