I have some nice ceramic piston trimcaps, but I don't have any panel hardware. The panel threads are about .1875" in diameter, but the thread per inch count is quite high--probably 48 (8 threads in <0.2"). By my figuring that could be a #10-48 except I didn't think that was a real beast. Any one with any ideas out there for this type of fine threaded hardware? TIA,
