Screw for mounting sheet metal studs?

[quilding]

Anyone know where to get so-called profile screws recommended by the gypsum and metal stud manufacturers?

Or is there an alternative name for these screws? I can’t find much info about them... So far, I've been using regular assembly screws because I don't have any fixing pliers, but it protrudes too much in some areas, causing the gypsum to crack.

If it's not too much work, you can pop-rivet them instead.
Tiring, yes, but you avoid buying the crimping tool.
Or rent a crimping tool?

So true. Will probably rivet the electrical boxes for the same reason, so it will probably be necessary to use pop rivets for the studs as well. Not much extra work actually.
