Yes they are different and your shaft is not heat treated so rough tight pianos will strip the loose thread. Two or more issues I think invilved here. Metric and standard inch thread and wearing out of threading die. The Boston thread is the largest in diameter that I have run into and the Sole the smallest.

I have a bunch of Hale and Watanabe tips. Are the female threads of the Hale tips different size from the Watanabe? It sure appears that way. I've got all these tuning tip parts and nothing seems to screw properly to one another...... :-( Terry Farrell Farrell Piano www.farrellpiano.com terry at farrellpiano.com -------------- next part -------------- An HTML attachment was scrubbed...
