One key aspect that sets 20mm chipboard screws apart is their coating. Most often, they are coated with zinc or a combination of zinc and phosphate, providing resistance against corrosion and increasing their longevity Most often, they are coated with zinc or a combination of zinc and phosphate, providing resistance against corrosion and increasing their longevity Most often, they are coated with zinc or a combination of zinc and phosphate, providing resistance against corrosion and increasing their longevity Most often, they are coated with zinc or a combination of zinc and phosphate, providing resistance against corrosion and increasing their longevity20mm chipboard screws. This coating not only enhances the aesthetic appeal but also protects the screw from rust, especially in humid environments.

The designation 1% 4% 2014 typically reflects specific characteristics associated with the screw's design and material composition, indicating its strength and suitability for particular applications. In many cases, the numbers denote the alloying elements in the screw's material, particularly in the context of steel to enhance corrosion resistance and overall durability. For instance, 1% might refer to the percentage of a certain alloy, while 4% could represent a different additive, both contributing to the screw's ability to withstand environmental stresses.

The use of self-tapping screws is a common and effective method in various industries for joining two or more materials. These screws are designed with a special thread that allows them to cut their own path into the material as they are being driven in, eliminating the need for pre-drilling holes. This makes them an ideal choice for situations where time and convenience are paramount, such as in mass production or in situations where access to the back side of the material is limited.
