What is the purpose of the Ejector Screw?

[Bruce_in_Oz]

If anything like the same screw on a No1, it will be slightly "hard" on the small part that protrudes inside the body. Once firmly in place and smothered in Suncorite , it should never work loose of its own accord. A tiny dab of "light" Loctite will certainly do no harm, if you are "worried".

Bubba is everywhere and Murphy was an optimist.
