Specialized fasteners called drywall screws are used to secure plasterboard sheets to metal or wood frames. They are essential to the building and finishing of interior ceilings and walls.
The fine threads on drywall screws are made especially to hold and fasten plasterboard panels to the subframe.
Shaft: Since drywall screws are usually used in indoor construction, where moisture may be present, their shafts are frequently coated or treated to withstand corrosion.
Size and Length:
To accommodate varying drywall and structural material thicknesses, drywall screws are available in a variety of lengths.
Common sizes for ordinary drywall applications are #8, #6, and #10. #8 is one of the most used sizes.
Type of Head:
Although Torx and square-drive (Robertson) heads are also utilized, Phillips heads are the most popular type of head for drywall screws. The type of head chosen is frequently determined by the available equipment or by personal inclination.
