I wasn't suggesting supporting a ton on one screw, I was just pointing
out that big screws are unnecessary. It is of course necessary to
ensure that the screw is soundly fixed in the wall which, I find,
doesn't depend much on the size of the screw. *Longer* screws often
help but *fatter* screws are not a lot of help.


I always think the older type screws were better as the root of the thread
was tapered. Modern screws are parallel therefore they don,t wedge tighter
as they are driven in - they also tend to cut into the plug rather than
force it open.
