Going nuts...

Help...
This thread. (Pun intended.) is a cry for help about ridiculously small metric nuts and threads.
Basically, I'm wanting to put a thread on the ends of 2 mm brass rod. However I'm not sure which metric thread would be suitable.
I've tried searching for a chart showing external thread size in relation to the size of the rod to be threaded, to no avail.
I'm sure someone must have such a chart or know what size die I need to do this.
Cheers,
Paul.

Maybe I'm missing something here but wouldn't a M2 die be the appropriate die to thread a 2mm diameter rod?

Edit added:
From page 246, Thomas J. Glover, Pocket Ref, Fourth Edition, Sequoia Publishing Inc., 2015 - "Clearance Holes for Bolts and Screws - Metric Series"
Bolt or screw size: 2, Nominal diameter millimeter: 2.00, close clearance hole: 2.10, normal clearance hole: 2.25, loose clearance: 2.40
bolt or screw size: 1.8, Nominal diameter millimeter: 1.80, close clearance hole: 1.90, normal clearance hole: 2.00, loose clearance: 2.15

Based on the above, and what you want to do, you might also be able to use a M1.8 die without turning down the rod if you were very careful!

By the way, Pocket Ref is a very handy little reference guide for everything from abrasives to zinc sheet gauge (first and last entries in the index). I highly recommend anyone with an engineering/mechanical/electrical bent have one. This particular volume is more taylored for U.S./North America. There is probably a similar reference directed toward Europe.

Thanks Phil,
I thought that M2 would be right, but wasn't sure. I'll get a M2 die and give it a go.
Regards,
Paul.

We had Zeus books when I was an apprentice, very handy little book, I'm not sure what happened to mine, I really ought to replace it
 
The following Google search brought up some tables. Sorry thought that I had posted this yesterday but was just sat waiting for me to press the post button!

It really is a mine field isn't it...
Good job I bought a set containing M1.0 M1.1 M1.2 M1.4 M1.6 M1.8 M2.0 M2.2 M2.5 taps and dies then. One pair of theses is bound to do the job in hand.
And all this just for a couple of handrails...
Regards,
Paul

That's because he's nuts, whereas I consider myself a bit of a stud, although my wife regards me as just a washer, but she cannot torque.

It would be sooooooooooooooo much easier..

If 'Metric' spanners were marked 'M6' 'M3' etc. :nerd::nod: After all, 'BA' spanners, are so-marked! :think::)
