[Shop-talk] Screwing steel studs?

[Jim Franklin]

I bought some hex head self-tapping screws for this, but the heads  
don't engage the driver enough to stop wobbling, and the screws take  
forever to drill through the metal, both which conspire to have me  
repeatedly smashing the drill into the fingers trying to hold the  
screw. Sometimes I get lucky and the drill misses my fingers, but that  
means I've moved quickly enough to slice my hand on the stud.

Is there a special screw for this? The 'net won't give anything up.

thanks,
jim
