Help me decode ETKA readouts

[dswalterwi at gmail.com (Don Walter)]

I'm kind of interested as well.

I do know for the bolts that the 1st number (M8) is the thread size,
the next number is the pitch of the threads, and the last number is
the length.  then they usually have some thing after that like z3 or
sw11.  I don't have any idea what those mean.
