There are two screws in the breech, one is 4-48 x 1/4", the other is 8-32 x 11/16" for a steel breech, 8-32 x 13/16" for the plastic breech.

They are flatheaded, right. It's the under the bolt. I want to replace it withna real screw.

Yes, the one under the bolt (4-48) is a flathead.

They are a  4-48 flat head with straight sides and flat underside (ie not v-shaped for a countersink type hole)

What's a "real screw" anyway?

Either a phillips or common flat headed screw.

We can't answer that type of question on this board because we are family oriented.  :P

Quick! Somebody give the newbie a screw!  Skip, do you have a file, a small block of wood,some sandpaper and a cordless drill motor? If you do, PM me and I will give you a "real" screw. You will have to file and sand a little off the dia. of the screw and a little off the top. In my picture I took a little too much off the top, but this was the first one that I made. The screw is a 4-48 SS.

McMaster Carr, Fastenal and many other industrial fastener suppliers.

You can't buy just one or two, be prepared for a bag of 25 or 50 -ish.

Originals are flat underside but countersunk replacements fit better.
