5. Corrosion Resistance Many 2% self-drilling screws are treated with coatings, such as zinc plating or epoxy, to enhance their resistance to rust and corrosion. This feature makes them suitable for outdoor applications and environments exposed to moisture.

Chipboard, while inherently strong, can be susceptible to damage if not properly secured. Fasteners play a vital role in ensuring that the pieces of chipboard stay together under stress and use.

Using the incorrect type of fastener can lead to stripped holes, poor support, and even failure of the assembled structure.
