Can someone let me have the part number for the larger grub screws? It was only a matter of time before one fell out and I couldn't find it. Can't find it on the website.
Thanks
 
I ask because here because Festool UK tell me they can't find a drawing for 577039.
 
Well, I believe this is what you are looking for. I don't which screws you need whereas there are two different ones. Here in the US they cost $2.12 each and $2.76 each.

Sorry, I can't see the numbers on the drawing. I'm looking for the screws for the bottom, expanding, rail. The numbers only go up to 4 in the description.
 
This is such a coincidence, never in my life have I ever come across an M7 thread, but just today I finally got around to fixing one of the mandrels on my rivnut tool, and lo and behold, it's an M7 thread on the retainer end!

Luckily i had the full range in my tap and die set!
