Hello,
I'm starting the gantry build, i assume the 2 beams must be bolted one with the other, and i ve think that could be done with a t nut and a (minimum diameter) hole for the hex key, screws will be M8 Din 7380. The gantry is about 1m, 1 tnut every 10cm x 2 rows. the 2 beams could be positionned differently...

or is there any reason to not make holes (stifness...) and do that differently ?

thanks for your comments.
