In trying to seat new agraffes that don't tighten in the proper position, has 
anybody every tried loc-tite blue?  How would that compare to CA?
The agraffe could be turned to the correct position then simply "locked" down 
with an adhesive of this nature that would still allow for future removal?

Ron addresses a better method, whch we also use. However, it got me thinking 
about why they need seating at all. An agraffe turned in loosely (short of 
seated) will, when strung, remain where it's put. I would expect the reason for 
seating it is to provide a solid termination, important just like the 
termination at the bridge pin. While it's true that a loose agraffe, especially a new, 
sloppily machined one, will rattle around; with even fifteen degrees of draft 
angle there is about 40-50 pounds of upward force holding the agraffe threads 
against the plate threads. Physicists, is there really any likelihood of 
agraffe movement, given the forces induced in the string by the hammer?
 
Always fun to rethink something that "everyone knows."
