M8 Super Self-drilling ScrewsAfter several years research and development, Sun Through brings this cutting-edge product: M8 super self-drilling screws. This unique product is not common in the market because the it required so much high level experience and knowledge to manufacture. We are even the first manufacturer bringing this M8 self-drilling screws in Taiwan.
However, only a large nominal size is not a big deal. What is surprising is its drilling capacity. In our test, it drills through a 20mm thick steel plate in 40 seconds, with 35-kg load and 2400 rpm. We design this product for super heavy duty applications.
The specifications of the screws in the images are: hexagon washer head, C1022, M8.0-1.25 X 80mm, #8 quick point and yellow zinc plating.
