The duc tape they sell today is crap. So, I was wondering, after the
second failure downstairs on the dryer

Try using the PROPER tape... DUC tape is *NOT* duct tape...

Use aluminum DUCT tape.
, ... has anyone use machine screws to
connect light AL exhaust ducting?

They will collect crap and should be avoided if possible.
