INTRODUCTION
Drywall screw as one of the common screw is widely used in the fastener industrial. It is also called as gypsum board screw. Self tapping drywall screw is also the most common type, and widely used. It can be used on thin sheet metal materials.
Drywall screws are primarily used to secure all or part of a drywall board to wood or metal studs.
Most drywall screws usually require a #2 cross head drill bit.
You can also use self tapping drywall screw in construction projects. Since self tapping drywall screw are quite brittle, they can break rather than bend. Its head breaks easily and embeds the displaced portion into the wood. This is why gypsum board screw should not be used for heavy or moderate construction tasks. You should avoid using drywall screws for outdoor projects such as fences and decks. You should only use drywall screws on light construction projects.
