Does anyone know of a supplier of M.E. thread steel setscrews, specifically ⅛" x 40? I need a couple of different lengths in fairly small quantities. Any suggestions gratefully received.

I think 1/8" x 40 ME is the same as 1/8" BSW so try looking for those instead?

I understand that ME threads are based on the BSW thread form so 1/8 x 40 and 5/32 x 32 are the same in both types (for the critical their could be a slight difference in the "Crest and Root" -

Reply to Michael, they are needed to fit existing tapped holes in cylinder head and crankcase of a model aero engine, and there's not enough meat to rethread with an alternative.

May just be easier to buy a bit of hex bar and a die and make your own, can't be that many in a small aero engine.
I wonder if you could get away with using 5-40 UNC which are 0.125" - 40tpi and at that size I doubt the 5 degree difference in thread angle will make a difference, even if it did you should be OK to tap with a UNC tap. Model fixings do 5-40 cap heads. If its an american engine than thats likely to be what was used anyway.
