Greetings all,
I am rebuilding a 17 meter beam I built about 35 years ago. At the time I used
slots and hose clamps where fastening element sections together but this time I
am going to use sheet metal screws. My tubing sizes will taper from 1.125" down
to .625" in 5 sections per side.
I can't find any information on what size screws to use unless I'm just looking
over it. I have seen a recommendation to use hex head screws rather than
typical flat blade or phillips head due to possible damage to the screw head
but nothing on screw size. I also wonder if self tapping would be a better
option than standard sheet metal type.
Any thoughts will be most appreciated.
Thanks & 73,Garry - K4OR
