I was wondering this.

It's never ideal of course, but sooner or later for small projects I
end up needing to end-screw (side screw?) into a plywood sheet. Is
there a "teethier" than normal woodscrew for the job?

A woodworker for small projects that I saw was using drywall screws
which just don't ever work well in any wood IME, but beats me about
plywood.

Particle board screws, aka low-root, work well if you drill a pilot
hole. A drill bit slightly larger than the root of the screw works
best. If you drill too small a pilot hole, the threads will try to
push the plies apart, weakening their hold.

Interesting idea. Given how much adhesive (epoxy?) is used in the
making of these things I'm tempted to tap out something coarse and use
a machine screw.

Machine screws actually work really well in tapped holes in tight
grained hardwoods like maple.

If you have to, prep the plywood by boring a transverse hole, blind if
you want one side to show, and cement in a chunk of dowel.
For 3/4" ply, a 5/8" Forstner bit, some glue, and the dowel has the
right
woodgrain to hold a transverse screw.

Threaded insert, maybe.

There are metal 'cylinder nuts' that will go in a bored hole and hold
a transverse machine screw. Is that what you're thinking of?

The cylinder nut solution is sometimes used in bedframes.

Google "threaded insert" and that's what I'm talking about.

I believe what you described is called a dowel nut.

Your reply was worth wading through tons of chaff to read - a great idea
that I will retain for future use!
Thanks!

I've always called them "cross dowels".

Tomato, tomato.

Of course, that saying doesn't work very well when read instead of
spoken. :-)

So you spell it "Tomato, tomahto.", silly.

Depends on the job but Drywall screws can work well for small projects.

They should not be used for structural support but used along with glue they
can provide quick assembly.

Most of all they are really inexpensive so

Use them for small things not for 2 story ladders P
