Source for precision or fine threaded rod in short lengths?

[nadsab]

Hi,

Does anyone know where I could purchase precision or fine threaded rod in short lengths? Around 60 to 120 threads per inch anywhere from gauge 4 to 8? In around 2 – 2.5” lengths?

And either matching nuts or threaded sleeves?

Thanks.

How about a 1/4-80 303SS 12' Bar. Also have taps.
How many of these parts are needed?
