Dave,
Thank you, not sure what I would do with a million screws

Never heard of pennies a pop obviously means something but never heard it before
I do have a string of thread guides, very good with a thread on one side a tapped hole the other, but they are not sold as far as I can find as small as you would need for repairing clarinets, they start at about 4mm upwards I would be looking for much smaller
Thank you Dave, everyone
Kaytee
