Best Metal Drywall Screw, Long Gray Phosphated Half Thread

Description

Metal drywall screws are classified according to length and pitch.

There are two common types of drywall screw lengths: S-type and W-type. S-type screws are designed for attaching drywall onto metal.

Their sharp points make penetrating the surface easier. W-type screws, on the other hand, are longer and thinner.

They are designed for installing drywall onto wood. Although drywall panels differ in thickness, it¡¯s usually sufficient to drive W-type.
