Of course the knurled nuts were all put in one bag some time ago. Noe it seems there are at least two different threads on the mounting studs and I dont have enough of the knurled nuts to come out even with the instruments. Looks like 8-32 but not maybe some are 3-BA but not all of them. Tried to order 3-BA tap and die from Metric & Multi-standard to no avail. Let's hear from the hive mind..I can't br the only one who has run into this.</div><div dir="ltr" data-setdir="false">Thanks</div><div dir="ltr" data-setdir="false">Ray <br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><img title="Inline image" alt="Inline image" src="cid:29186742-3066-b3a5-2b58-418dacffff95@yahoo.com" class="yahoo-inline-image" style="max-width: 800px; width: 100%;" draggable="false" data-id="<29186742-3066-b3a5-2b58-418dacffff95@yahoo.com>"><br><br></div></div></body></html>
