I don't know about Yamaha, but it was certainly the gimmick 
the competition used to suggest that these pins would chew up 
the pinblock and the pins would be loose in short order. 
Unfortunately, Yamaha had some problems with loose pins in the 
early imports into this country, which lent credence to the 
thing. Cut thread pins don't, in fact, chew up pinblocks.

BTW, remember the rolled thread pins APSCO used to sell, that 
snapped and popped in the block no matter what you did? It's 
Denro blued for me, but does anyone even sell other than cut 
thread pins anymore?
