After readng this I went and looked for information about the screws. Everything that I have read stated the screws were made from soft steel, A.I.S.I. 1020 which is a low carbon steel well suited for cold forming or case hardening. All the scews were made of such metal.
In Brophy's book "Plans and Specifications of the L.C. Smith Shotgun" he states on page 11 that " most screws were made from drill rod and the heads were polished".
Also the buggered screws that I have repaired by filing indicated that this screws were soft as the file cut them easily. Also if these screws were case hardened/colored the chances of them fracturing, especially the front trigger plate housing screw would be greater as more torque is applied to this one.
