Odd Thread size

[CarstenP]

We need help to identify a thread with the following data:

- Major dia. 0.374"
- Pitch dia. 0.365"
- Minor dia. 0.356"
- Pitch 0.03099"
- Pressure angle 45degree
- Helix angle 1@32'54"

Does anybody know what thread this is or where I can look it up?

Thanks

Sounds almost like a weird buttress thread for an instrument?

Looked at it under a comparator? Checked that it's not multiple lead?

it is for a insulin device.

checked it with a comparator. no multiple leads

One standard medical thread is 1/8 NPT and it is real close to the specs. you gave.
