well you found a work around which should suit into the future.
many B's incl your and mine are made in Canada where different types of products are available or determined by practice or code
that could incl pvc pipe fittings
the Robertson R1 and R2 screws are used extensively throughout my B being common for CDN cabinetry and electrical.
My Previous owner didn;t know this and just about every cabinet screw on my B took a 1/8 to 1/4 turn to tighten up and get all the squeaks out- a few screws he buggered up with wrong tool.
I replaced by buying some matching screws while on a trip the Canada.
glad you have a fix!
