The main difference of this screw lies in its #1 drill point tip, whereas standard self-drilling screws typically use a #3 drill point. The #1 drill point is mainly designed for thinner metal sheets ranging from 0.5mm to 1.5mm and softer materials. It offers lower drilling resistance, which significantly improves installation efficiency.
The color-painted head not only provides a visually unified and attractive finish but also offers additional corrosion resistance. This product is currently very popular in the Central Asian market.
