The above link shows a butt joint made with 1" Triton pocket hole
screws and the Triton double pocket hole jig.

The wood is 15mm thick on the short side.

I did several test joints using thicker wood, e.g. 18mm and they
worked a treat.

But as the picture shows, on the thinner wood the screws stand proud
by about 1.5mm.

Is it just because the wood is too thin for pocket holes?

I can of course file the proud bits flat, then insert the provided
filler plugs and finally sand down. The little bit of bright metal
showing after sanding down the plugs wouldn't matter.

But it's annoying.

I checked and the screws protrude from the rail exactly in the centre
of the butt piece as it should be.

Alternative: Kreg pocket hole screws appear to have more "compact"
heads instead of the rather large integral washers on the Triton
variety.

So could I use Kreg screws instead?

Thanks.
