Drywall screws made of hardened carbon steel or stainless steel are used for fastening drywall to wood studs or to metal studs. They have deeper threads than other kinds of screws, which can prevent them from removing easily from the drywall.
Drywall screws are usually bugle head screws with spaced threads and sharp points. Classified by the pitch of thread, there are two common kinds of drywall screw threads: fine thread and coarse thread.
Fine thread drywall screws have sharper points, which make them easier to screw in. They are commonly used when fastening the drywall to the light metal studs.
Coarse thread drywall screws have fewer threads which make them hold tighter and screw into place faster. They are commonly used when fastening the drywall to the wood studs.
Besides, special drywall screws are manufactured for specific purpose. When fastening the drywall to the heavy metal studs, you'd better choose self-drilling drywall screws, no need to pre-drill holes.
Meanwhile, There are collated drywall screws. They can be used on screw gun, which speeds up the installation.
Moreover, there are various coated drywall screws which can protect against corrosion.
Drywall screws are the best way to fasten the drywall to the base material. drywall screws provide the perfect solution for different kinds of drywall structures.
Mainly used for fastening the drywall panels to metal or wood studs, the drywall screw with fine threads for metal studs and the coarse threads ones for wood studs.
Also used for fastening iron joists and wooden products, especially suitable for walls, ceilings, false ceiling and partitions.
The special designed drywall screws can be used for building materials and acoustics construction.
Black-oxide steel screws are mildly corrosion resistant in dry environments. Zinc-plated steel screws resist corrosion in wet environments. Black ultra-corrosion-resistant-coated steel screws resist chemicals and withstand 1,000 hours of salt spray.
