I'm building a spoil board and planning on securing it to the aluminum extruded bed. Does anyone know the size of the t-nut or slot nuts that fit? I measured and looks like 9mm, just not sure. I would like to use the slot nuts similar to the ones used by Incra tools.

I just used bolts, if you add a washer then the bolt can't turn and nylock nuts and washers on top, check my hold down board here. I really like the Rockler Track and hold downs

I believe these are the correct T Nuts.

I bought mine from Radiospares a few years ago. Just had a look and can't see them. I have a pic somewhere.
I'll post it if you like. Mine have a M6 thread.

Edit: I found them!

Thanks, The Chinese 6040 uses a base of extruded aluminum and I finally found that it got 10mm grooves, so I got the square nuts from Amazon. They're 10mm M6.

Thanks so much. That's the slot nuts I was looking for. As I said earlier I was able to find these. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

No Worries. Yes, my machine is a 6040 so its bed is extruded Aluminium.
I hope they do the job for you.
