We have screws & escutcheons for certain revolvers and guns that can accomodate the screw going through the grip panel and gun frame and seating into an escutcheon (or nut) on the opposite panel...at a cost of $5.50 for the set. We have a link on the left side for ordering these items of choice.
We offer the domed head for buttplates and the flat head for gripcaps.
