Angle is the easiest. Be sure to thermally isolate each attachment point. If you do not the 80/20 will be close to the van steel temperature. Bypasses any insulation. You do want to ground the structure in one location.It looks like, from wading through a lot of this thread, that the consensus to attach the 8020 to a wall is to attach angle to the wall, then attach the angle to the 8020? Has anyone figured out any other elegant ways of attaching it, such as some sort of countersink screw, with a small head diameter, through the center of 8020 to a rivnut/plusnut? Getting geared up to start some of my 8020 work and trying to figure out the best and cheapest way of accomplishing this. Thank you in advance!
Yes, you can use a button-head hex-drive screw + washer in any slot with a 7 mm access hole to drive it in from the far slot. I did all my internal frame attachment points in this manner using 4040 extrusions and class10.9 M8 hardware.
