+1 for toggles or another mechanical fastener.Drill a hole and insert a toggle bolt - the kind with wings.
tap-con. drill and screw.:icon_thum quick easy and they hold. you can get them in philips head and hex head. be sure to get the drill bit that is made for them.
I am a fan of Tap Con also but I would caution that you be sure drilling dust is vacuumed/blown out of the hole before you drive your fastener. DAMHIKT :eusa_doh: :wsmile:
and if you blow out the holes wear a mask.
Thanks ALL,I will look into the Tap-Cons, thanks. 2nd ?
These are support colums, should will drilling them create any potential issues I should be aware of?
