FREQUENTLY ASKED QUESTIONS

  • Q What links should be paid attention to in the screw production process?

    A
    As we all know, no matter what kind of screws, they have become very important fasteners in our lives, the small screws play a pivotal role in any field.
     
    Self-drilling screws have also been recognized in the industry because they can adapt to any harsh environment. Of course, no matter how good the self-drilling screw is, we need to focus on the quality control process.
     
    First of all, we have specific requirements for the rinsing process of SDS screws, but this process is often ignored by many people. The rinsing step must be done after cleaning with silicate cleaning agent. When tempering and heating, the stacked SD screws should be qualified, otherwise the drilling screws in the quenching oil will be slightly oxidized. If white residues appear on the surface of the drilling screws, it means that the inspection during the operation is not careful enough.
     
    And then, the heat treatment of self-drilling screws must be strictly controlled. According to different products, different diameters, different lengths, and combined with the customer's final application scenario for the screw, it must be based on different heat treatment processes.
     
    Tsingri specializes in the production of door and window screws, curtain wall screws, drilling screws, composite (Bi metal) screws, stainless steel drilling screws, high-strength carbon steel screws, stainless steel fasteners, photovoltaic bracket bolts, light steel house screws, solar panel special screws, etc.
