Yes, I think they're wood screws. I usually use a piece of wooden toothpick and some wood glue - worked great on my Fender.
Even though they're wood screws, I'd expect the thread pitch to be different depending on whether they're metric or U.S. sizes. I suppose if the original strap pins came with screws, they'd be metric; did Alembic use those or choose their own U.S. sourced screws?
I'll remove the screw that's currently in there and measure it, and choose the current Schaller S-Lock size accordingly. I have toothpicks and glue just in case
