I'm not a 601 builder, but I drill a lot of holes. I measured several
AN3 bolts furnished by ZA last night. Smallest was .187 and the largest
was .1885.
One way to help visualize slop is instead of diameter over, picture how
much over per side. For example, if your hole is .003 oversize, that's
.015 of space on each side of the bolt.
And you already know this but......don't just believe the the size drill
you buy will bore the stated size. Many are poorly ground with
uncentered points. And your technique makes a difference. Measure test
holes, not the bits.
A guy came into my plant and asked "how can I make this bit drill
oversize?" That's easy, let me sharpen it.
I am adding metric diameters to the list below. They are available for
about the same money,
Regards,

Just a minor correction, I'm sure you meant .0015 per side.
