This is the Putco MOLLE Plate model.
The hole on the original part is 0.2" for the screw hole and 0.3" for the brass insert.
The hole in this model is 0.26". This will allow you to use this as either a spacer with some tolerance for the screw or will leave 0.04" of plastic for a plastic insert to bite into.
