I am not certain about his, but I have heard that most (if not all) tuning tip threads are tapered. Anyone know for sure?<br>

<pre style="font-size: 9pt;"><tt>Anyone know what threads the Watanabe tip receives?<br>
<br>
The stud onto which the tip screws measures 9.49 mm X 0.85 pitch in<br>
metric. I'm guessing that's almost certainly *supposed* to be 9.5 mm.<br>
<br>
9.5 mm is almost 3/8" -- just 0.0013" shy of it, in fact. A standard<br>
3/8" with 30 threads per inch corresponds exactly to the stud<br>
threads...except for the very slight difference in diameter.<br>
<br>
So I'm thinking the 3/8" will work fine. The tip has enough play in<br>
it that it should screw on without any problem.<br>
<br>
Anyone know offhand?<br>
<br>
Thanks,<br>
<br>
