If you really want to get "nut-so" and it is a tight fit (i.e., bolt to WAF hole w/interference) you could always toss the bolt into your deep freezer before insertion. You should definitely see a reduction greater than 0.0005" - of course you could do a trial with a calibrated micrometer (if you can afford one with the proper resolution - remember the 10:1 rules of precision) and see how much reduction in diameter you actually get between 70F and =20F (where I keep my deep freezer - steaks last forever). As usual, your results may vary.

Sometimes us "high school physics engineers" survive in spite of ourselves.
