no matter what it'll tear out after a while. your best bet is a tight fit on the threads with sheet metal screws and foil tape to keep it in place so the wind wont tear the bolts out.
you can also use twist lock b vent if you can adapt to it.

thats why i was wondering if perhaps it would be best to get long bolts that go end to end and then putting a nut on it. see the top parts that are above the roof aren't a problem. but under neath what happens is the roof moves a little in the wind and yanks and twists the lower segments which causes them to come out. the stove has some holes to put screws into the pipe and then of course i could put some in the other joining parts of the pipe, i was thinking maybe even a bolt right under the roof panel that would sort of keep the roof propped up a bit. i just want to be sure what to do before i start because i don't want to be putting holes in the pipe that end up being wrong.
