Self Drilling Screw through the point of the screw to be drilled (steel plate, aluminum plate, etc.) for cutting, and then directly tapping with threads, and then locking. The most critical step in this seemingly simple fastening process is the initial tapping and cutting process. Whether the TEK screw can penetrate the plate and whether the drilling is rapid, these are related to the drilling point of the TEK screw.
#1, #2, #3 are used to drill and fasten in steel plates. #5, #7 are used to drill and fasten in thick steel purlins. According to the thickness of the drilled object to choose the corresponding drilling point type is the most reasonable, in order to maximize the drilling time and fastening efficiency.
Generally, for customers of customized self drilling screws, we UNITEK will first ask the customer's requirements (the material of the drilled plate, the thickness of the plate), and then give the customer reasonable suggestions to choose the appropriate drilling point type.
