What is the purpose of the Ejector Screw?

[Neuraleanus]

I have lots of long ejector screws (and the rear mounting screw for the PH5C), they are over length and will need trimming and are in the white. I bought them nearly 30 years ago from a local engineering company here in the UK. PM me your address and I can send you one.

Thanks for the offer. I'll keep your offer in mind. I have a bunch of BA threaded screws, and a set for a PH5A, on the way so I'll give these a try first. I was able to find a source for these here in the USA: https://britishfasteners.com/
