No need Dugly. The flange on a (aluminum or steel) 10-32 poly nut is .022". Hardly a crisis.
If you want them totally flush, simply use a step-drill to make the proper hole size and go to the next cutter up on the drill and make a shallow 'chamfer'.
I replaced every single sheet metal screw on my ERA with these and they are a God send- on removable access panels especially. All are now button-headed allen machine screws in 8-32, 10-32 and 1/4-20.
