    What is the role of tapping screws?

    Self-tapping screws are mostly used for connection between thin metal plates. The thread is an ordinary thread with an arc-shaped triangular cross-section, and the thread surface also has high hardness. Therefore, when connecting, the screw can also tap an internal thread in the threaded bottom hole... read more

  • Why are self-tapping screws always loose?

    Why are self-tapping screws always loose?

    1. The thickness of the fastened parts is greater than the thickness of the head of the self tapping screw. After the tapping screw is tightened, there is still a part of the screw thread that does not enter the threaded hole. In this case, the self-tapping screw can definitely be tightened. 2. The ... read more

    What are the key points of the performance of stainless steel fasteners?

    1. High temperature resistance of stainless steel fasteners Since the hardness of stainless steel itself is relatively strong, the fasteners after production have strong anti-oxidation ability, and can work normally at high temperatures, and will not be interfered by too much high temperature. If th... read more

    What are the technological requirements for self-tapping screws?

    Since self-tapping screws are required to have the performance of self-tapping low-carbon steel plates, they require high-hardness surfaces to achieve cutting and extrusion capabilities. At the same time, there must be sufficient heart strength and toughness to prevent distortion or twisting during ... read more
