Hit an estate sale this morning and scored a few nice items I can use.
One thing I bought, 'just because' was a #10-64 die with two matching
taps. Figured they'd cost me a bloody fortune if I ever needed them, and
a couple bucks would cover the cost of inventorying them in the
meantime. G

Anyway, anyone have any idea what might use a 10-64 thread?
Some sort of musical, or scientific instrument thread?
Or just some oddball application?

Just for someone who needs fairly fine adjustment screws.
Granted, it is pretty close to 0.40mm (actually 0.3969mm) which is about
a "tenth" (0.0001") off -- close enough for a lot of things.

Enjoy,
DoN.

Sounds like a micrometer thread size.

Na, mics are 40 TPI or.025 per rev.

Nah. One turn of the thimble is 0.025 x 40 turns
is one inch.

Maybe a fractional micrometer? G

Hmm, probably right, that was the only thing I could think of. I was
just curious if anyone knew of someplace this thread was commonly used.
Custom taps and dies are not cheap...
