Yeah. I think at this point, if I can’t find the screws, I may talk to a machinist friend and offer to split the cost of a screw-cutting machine with him and we’ll start making our own damn screws. A couple grand will pick up a working used Browne & Sharp machine. Only snag is they’re 480V 3-phase.

As someone said, there may be a suitable answer in a metric size. I’ll poke at that next.

Lee Valley sells some “small steel round-head screws for tansu hardware” but they’re Philips head. It would probably be quicker to buy those and saw slots in the heads. Or buy their black brads for the same hardware and cut threads and slots.

May you have the day you deserve!
