HI  Ed
      All the 7/32 " replacement  agraffes out there from piano- tek,Steinway 
or where ever are, I believe, of  German origin & none that I've measured are 
the actual size of the originals  but slightly smaller as you say. We still 
use them however & I've  cranked em sufficiently tight without ever a one being 
stripped. We've installed  dozens of sets. I forget the amount smaller that 
they are and I was alarmed  at first However I feel more secure installing 
these than reusing old ones which  I have had broken ones after the fact.
   Do you have a supplier with a true dimensioned  part? If so I'm all ears.
  Merry Christmas All

Greetings, 
That will be a 7/32" thread.   Be warned,  for some obscure reason, modern 
agraffes of this  dimension are not cut to the full .218" thread.  I don't 
know 
why  this is so, but last year, I had an impossible time finding a "7/32""  
agraffe that had thread larger than . 212".   This may not seem  like much, 
but is 
sufficiently undersized so that the threads will strip  if you try to torque 
them as tightly as the ones that came out.  Jon  Page saved me with some 
older 
spares, which I had to use after two new  ones stripped.  
Good luck,
