Lost Motion Grommet Curiosity

[BSimon999@AOL.COM]

I soon have to install a set of the square headed lost motion adjusters, 
containing a square fiber insert, into a Gulbransen spinet.

Whenever I do this job I find that so many of the adjusters are so badly made 
that just trying to screw them on is either impossible and tears the fiber 
square apart, or they disassemble themselves.

I was planning to run a tap through the fiber square to "pretreat" the 
adjuster and have fewer problems during istallation, but I have no sample of 
the wires they go on.

Does anyone know what size thread the wires have?  I seem to remember it is 
something like 6-32, ( #6 size, 32 threads per inch) but it might be an 
oddball size. 

I would appreciate any info from someone who can compare the threads to a 
known size. 

Thanks,
