[pianotech] Wing nuts to square Nuts

[johnparham at piano88.com]

If you run into this issue a lot, you may want to invest in a "thread
gauge."  It looks like a feeler gauge for spark plugs. By trial and
error, find the sample that fits your threads and you've identified the
number of threads per inch (for fractional sizes).  They make fractional
and metric gauges.
