It's real easy to tell if these are B30s with a magnet.

They are generally used to bolt sections of a jet engine together and were
the subject of a huge counterfeiting scare in the early 80s.

****** So Ben,
is a real B30 magnetic, ie, attracted by the magnet ?

Dave McCandless



A real B30 is made of Inconel 718 which is not magnetic.  Sorry, It wasn't
supposed to be a trick.
