Anyone know where....

I can get some 3mm knurled headed screws to replace the grub screws in my astrotrac polar scope?

I've been looking at this guide:

http://www.fredmiranda.com/Buzz/Collimating%20The%20AstroTrac%20Polar%20Scope.pdf

And the info provided by StuartJPP here:

I would quite like to find a UK source for the screws used in the first guide.

Any help will be most appreciated.

Try a local bolt/fastener company and see if they have some

I found brass ones from an ebay source but it seems to have dissapeared now. Why not try the plastic ones they should work fine as they are not load bearing.

Thanks guys, I've done a bit of digging around and found these websites:

Being useless at this sort of stuff I assume an M3 thread is a 3mm metric thread. Just need to decide on a length and take a punt.
