Long Gray Phosphated Half Thread Metal Drywall Screw

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.
