Dremel thread size??

While attaching the flex shaft to a Dremel rotary tool you screw a cap (the one with a square hole in it) on the motor shaft. Can anyone tell me what size thread that is? A couple of years ago I found a site where machinists were in disagreement as to what it is. Obviously it isn't something the big box stores will stock but maybe a good old fashioned small town hardware store would! I've got some ideas for my own attachments to the shaft but thread size is holding me up. THANKS!!!

My local hardware store is pretty used to me bringing odd stuff into the nuts'n'bolts section and trying stuff right there

I brought an exhaust manifold in once to find the right stud

Talking You've been working on this a couple of years!...... I thought I procrastinated.

sandy,

Most locking collars have a super fine thread to allow maximum torque to be applied to the bit.
It is doubtfull you will find a common thread to fit.
A machinist will have a thread guage to size it for you.

If you have the cap and just want to make up your own attachments, would it not work to have a fine thread bolt welded to a shaft that fits the Dremel tool?

I have found that the attachments from other manufacturers do not seem to fit so I was wondering if Dremel has used a unique size so you have to buy their products to fit. Just a thought.
