Product Description

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, we can offer 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
