with a glued joint, if you pull straight away from the surface, then
you probably risk pulling some fibres from the surface (or the whole
outer layer of the ply). If the force is more parallel to the surface,
then there is probably less risk.
Fasteners for load vertical to the surface don't help much: the head
of the nail or the screw would simply be pulled through the wood
(unless it is enlarged by a washer). Loads parallel to the surface are
held very well by a fastener, though.
