on the first set of platenuts i set on the right spar, the shop head is just SLIGHTLY small in the gauge. on the left spar (don't know why i didn't think of this for the right side

), i added a thin washer under the flush set, and they are set perfectly in the gauge. my question is, should i go back to the right spar and set all of them just a little more, or leave 'em? i don't want to upset the new metal composition of the previously set rivet, but does it matter enough to work 'em again?
