Screws provide a stronger hold, but cost a bit more than nails and usually feature a Phillips head. 

• Coarse drywall screws feature coarse threads to secure gypsum board to studs.
• Fine drywall screws feature smaller heads and are used to secure drywall to metal studs.
• Self-drilling and pan-head screws can be used with metal studs or frames.
• Trim-head screws are used to attach wood trim over gypsum boards.
• Screws can be driven in with a drill or electric drywall screw gun.
