to remove the chipboard particles when countersinking. The
galvanised coating is suitable for most outdoor applications.
chipboard screw or particleboard screw is a self tapping screw with a thin shaft and coarse threads. Chipboard is a made up of resin and wood dust or wood chips, so chipboard screws are made to grip this composite material and to resist withdrawing. The screws solidly fasten chipboard to chipboard or chipboard to other materials such as natural wood
Chipboard screws come in a variety of lengths and can be used to fasten chipboard in variety of applications. Average length chipboard screws are often used to join chipboard flooring to regular wood joists. Smaller screws may be used to fasten hinges to chipboard cabinetry.

Average screws are 1.5 inches (around 4 cm), small screws are usually ½ inches (around 1.5 cm), longer screws are 5 inches (around 13 cm).
