Particle board screws tend to have thin but wide threads (so they "cut
in" and hold better in fragile materials like PB and MDF). *"Standard"
wood screws tend to have narrower threads, but I'm seeing more and more
construction screws that look similar to particle board screws.

I've used construction screws in ply/mdf/PB and solid wood.
Noncommercial use, but it seems to be holding up fine. *I like the Spax

Since I also live in Canada, I always seem to end up with Paulin
screws! Anyway, it seems like construction screws can be used
instead of particle board screws. So really its a matter of selection
and cost.
