X-Frame scope base barrel screws

[rbabbitt87]

I have a 7.5" Performance Center 500, and I have no present intentions of mounting an optic to the barrel. As such, I'd like to fill in the base mounting holes, preferably with Torx screws. Does anyone have the dimensions, or a resource to order such screws from?

They are standard 6x48 plug screws, ask any gun shop. You will probably have to settle for blued though.
