Which are the most useful sizes?

I've just come away from helping set up a temporary kitchen. I was
delegated the task of making a frame and 4 legs to carry a ss sink.

I decided to just pin joint a frame of 2 by 2s with screws. Now these
were just standard gold coloured screws from a shed, not quite like
the screws I remember but they did drive with no clearance/pilot hole
but then not unexpectedly didn't pull the joints tight.

I've used some other, black screws recently that might be the
screwtite type, a thinner shank with screw flights considerable wider
and a bugle head rather than simple countersink. As long as the
unthreaded part is the same length as the batten being screwed these
will pull tight.

Given that you probably only need 30mm of screw in the anchor part is
it possible to buy screws like this but with only 30mm of thread and
then various shank lengths?

I'll need to address this when I next visit unless the sink has
already collapsed.

With no clearance hole I cannot see how a screw can pull two pieces
together. Imagine if you created a deliberate space and then drove a screw
through and tightened it - then the thread would be good in both pieces and
they would not pull together. Your idea of a long plain section is a sound
idea but in the meantime I think a clearance hole is the answer.
