just
wondering what the best way of fixing it was?, nail it or screw it
obviously with countersunk screws, its to be covered with an EDPM
membrane rubber roof covering.


Another alternative here.
The shanks are twisted 7 therefore hard to pull out.

Those are designed for fixing things like corrugated sheets, not
fixing a desk that will be covered after. So completely unsuitable for
use under a EDPM roofing membrane - the protruding heads will damage
the covering.

or deck even :-)


The people who supplied my EDPM kit warn against using using nails
in case they work loose over time. Only screwing is acceptable
to them or the guarantee would be invalid.
