Electro/SP, easy access grip screws

These are neat. Rounded, button-head grip plate screws. I know they will fit SP grip mounting holes, which are 6-32 x either 3/16" L or 5/16" Long depending on grip panel thickness. So if your grip panels use 6-32 screws to hold them on, they should fit...I might have to pick up a few.
