They may be 55 degrees, but they sure as heck aren't 1/8" OD -- the
shaft measured too close to 3mm to be anything else, and the OD of the
threads was definitely 3mm, too.

The limits on the major diameter of a 5-40 UNC-2A thread are .1242/.1191
-- within .001 of 3mm.

Hmm. Clearance hole for 5-40 is 1/8, this is definitely smaller than
that.

dont you just hate it when you cant identify a thread. I mean it sits
there bare naked before you, no pretences, and all it fits is the
thread it was mated to. none of the taps and dies of supposedly the
same size come within cooeee of it :-)
