[AMPS] go figure/Murata mm vs 1/4- 20 threads

[Jim Zellmer]

If the threads in the Murata caps are metric and the 1/4 20 fit, you
probably snuck by with a length of thread connection.  A 2mm pitch metric
thread has a lead of about .052" per revolution.  vs. about .050" per
revolution for the 1/4-20 thread.  You can get about 3, may 4 turns before
things bindup because of thread interference caused by the differnce in the
lead of the metric and UN thread.

73,
