The major diameter for #8 threads is .164"
#10 is .190"

This may sound like nitpicking, but .164 is the *nominal* size of a #8
screw thread. The *major diameter* (the actual diameter at the thread
crests) is determined by applying an allowance to the nominal diameter
to insure interchangeability. Major diameter for a 2B thread is .1571
to .1631, which is the number the OP is looking for. As has been
mentioned, 5/32 is close enough, 4mm would fall in the spec.
