Self drilling screws can be drilled on a variety of basic materials to achieve rapid splicing assembly, and strong adhesion, not easy to loose off, high coefficient. In construction and decoration projects, various materials can be combined closely, resulting in smaller costs, and obtain a higher degree of trust, which is an economic metal fastener. Mainly used in the steel structure of the color steel tile fixed can also be used for simple construction of thin plate fixed. The product features are as follows: 1, has good toughness: C1022A material, after heat treatment technology, to avoid drilling nail internal hard caused by fracture. 2, corrosion resistance. 3, the appearance of the surface can be customized according to customer requirements: the surface of the self drilling screw has electric galvanized, ruspert, dacromet, phosphating, spray painting and so on. 4, high strength: After heat treatment, the surface hardness of the self drilling screw can reach more than HV580-HV750, so as to complete the fastening process of self-drilling and self-tapping teeth more quickly. Save time and improve work efficiency. 5, inexpensive. Most of the process is done in the factory and the prices are very competitive.
