I use two of the screws Tom has shown. These have 7/16" washer heads. A 1/4" to 5/16" hole will give you lots of wiggle room for fine tuning the clearance. I have 3/4" hardwood fronts that are held with these that have seen years of service without issue. If the pulls allow penetration between box and front, all the better for fixing the position once you're happy with it.
