Tek screws are specially designed screws that feature a drill point at their tip. This drill point allows the screw to create its own hole as it is driven into the material, which is especially beneficial when working with thick steel. Unlike regular screws that require a pre-drilled pilot hole, Tek screws simplify the fastening process, saving both time and labor costs.

Self-drilling screws have become a popular choice for many construction and engineering projects due to their convenience and efficiency. These screws eliminate the need for pre-drilling a hole before inserting them, saving both time and effort. One type of self-drilling screws that is commonly used is the 4% self-drilling screw.

The white wafer head of these self-drilling screws is characterized by a broad, flat surface that provides a wide bearing area. This design helps distribute the load more evenly, reducing the risk of damage to the material being fastened. The head is typically finished in a white coating that not only enhances aesthetic appeal but also offers a degree of corrosion resistance, which is particularly beneficial in outdoor applications or areas exposed to moisture.
