Kreg - Pocket Hole screws by Hillman (Rating: 5)

I notice last time I was at Lowes that they started carrying Pocket hole screws by Hillman. Ialso notice that they did not carry the pan head style. It was my understanding that you need pan head if you wanted to cover the screw with a plug. Everytime I use the washer head it sticks up out of the hole. Am i correct?
