The adjustable angle support can be used to connect 20x20 aluminum extrusion together. Rather than being at 90 degree, this piece can connect two beams with the angle you wish. You can tighten the angle with the side screw.
The half that connects to the side of the extrusion simply uses a M4 or M5 x 8 mm long screw + T-nut. For the half that connects to the end of the extrusion, you'll need to tap the 5 mm diameter center-hole of the extrusion and screw directly in.
