invader screw to replace big pole pieces

[natelc1979]

Do they make black screws that would fit to replace the big cap screws on the invader. If so what size diameter would I need?

Dimarzio size hex-bolts like on a superD were known to work fine, and they used to sell them direct for cheap, but these days they are not doing that.
Hopefully someone here knows a good aftermarket source and the right size. Sorry I'm no help.
