Aluminium c section.....where to buy

[mike os]

If need some c section with a 5 to 6 mm slot to take an m4 screw head any idea where it will get some?

Google is not being very friendly

If you search for 10mm by 10mm channel you should find it with a 2mm wall thickness.

This should give you a 6mm ID

Do you mean t-track?

Because I thought c-channel = u-channel = channel?

If you want something that will keep the bolt heads captive then as above, it is called T-Track, C section is channel. I have never come across T-Track with a 5mm to 6mm slot width, you will end up with very small contact area on the bolt head?
