Parker Hale Scope mount Screws

[bush1]

I have a Parker Hale A29 scope mount and a #4 Sporterized Endield that is drilled for the A29. It has the correct screws but the allan heads are buggered on 2 of them.

My research shows these cap screws are 4BAx1/4" and are 38.5 tpi. Can anyone confirm this? Also any idea if I can source these in Canada or will I have to source them in the UK?

Thanks, I’ll look there. I guess I had better find out first if in fact these screws are indeed 4BA. I just assumed that by looking at old posts. I’ll take them to my friends machine shop and hopefully he can identify the threads.

They shouldn't be allen head screws
