low profile fasteners

I am looking for a suitable fastener to secure a thin composite [graphite/epoxy] panel about 1~2mm thick to an internal aluminium structure. Blind assembly.
Appreciated if someone could enlighten on the possible source.
thank you.

how about adhesive? epoxy based adhesive is very strong

Anyway, if you must use fasteners try HillCo Fasteners. www.hillco.com if I’m not mistaken.
