DRYWALL / GYPSUM SCREW & CHIPBOARD SCREW (DIN7504 / DIN7505)

DRYWALL / GYPSUM SCREW & CHIPBOARD SCREW (DIN7504 / DIN7505)
Drywall screws have deeper threads than regular screws, which prevents them from dislodging easily from the drywall.

They are made of steel and require a power screwdriver to drill them into the drywall. In addition, drywall screws are often used along with plastic anchors that help distribute the weight of the hung object evenly over the surface.

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 screws into the wood at least 0.63 inches (1.6 centimeters), and for S-type screws to penetrate a metal stud to a depth of 0.38 inches (0.9 centimeters) If you are screwing through multiple layers, make sure the length of the screw is enough to penetrate at least 0.5 inches (1.3 centimeters) into the second layer.

APPLICATIONS

When should we use Drywall Screws?

When installing drywall to metal, you must use drywall screws along with a specially designed drywall screw gun. Since drywall screws attach more securely, you can use fewer screws and space them farther apart -- 12 to 16 inches (30.5 to 40.6 centimeters) is sufficient.

=========
When should we use Chipboard Screws?

Ideal for chipboards and wood, they are often used for cabinetry and for flooring. Common length (around 4cm) chipboard screws are often used to join chipboard flooring to regular wood joists. Small chipboard screws (around 1.5cm) can be used to fasten hinges to chipboard cabinetry.
