Nuts and Bolts
Posted: Fri Dec 19, 2008 8:58 am
Hi,
Recently i was at the dollar store and picked up a set of nuts and
bolts. The package was not marked as to the sizes of the nuts and
bolts but there were 100 pieces so i thought that was a pretty good
deal.
I got home, opened the package, and found that (to my surprise)
all of the bolts had enough matching nuts and they fit perfectly.
I expected to get a roughly equal amount but planned on missing
some nuts or whatever.
So anyway, the sizes APPEARED to be 8-32 and 10-32, but after
trying a standard 10-32 nut on the package bolt it was very
tight, and the package nut was so tight on the standard 8-32 bolt
that it wouldnt fit at all.
Any idea how i can verify what sizes these are without buying any
new hardware? I have a good 1" micrometer, but the size differences
in diameter are very small like 0.003 inches and the threads
per inch vary by only a tiny fraction too: 32 TPI for standard,
31.75 TPI for the metric.
I usually use American Standard bolts and nuts.
