Self-tapping screws are often seen in metal plates with relatively thin links (steel plates, saw plates, etc.). Due to the high strength of the threaded surface of the self-tapping screw (≥HRC45), when linking, the self-tapping screw is screwed into the connector that has been made with the threaded bottom hole in advance, so that the inner thread can be tapped in the threaded bottom hole of the link The thread thus completes the connection. There is a special screw that has better working performance than ordinary self-tapping screws and can even replace machine screws-self-tapping pin screws are often used for links between thin metal plates. The difference between it and the ordinary self-tapping screw is the ordinary thread with the arc-shaped triangular interface with higher hardness. This kind of excellent screw with low screwing torque and high locking performance, of course, can also tap the internal thread in the threaded bottom hole to be connected like a normal screw.
The wallboard self-tapping screws are used to connect the gypsum wallboard and the metal keel during decoration. This kind of screw has a high hardness (≥HRC53) double-threaded thread, which can be quickly screwed into the keel to form a connection, even if a prefabricated hole is not made.
Self-tapping screw is a kind of screw with a drill bit. It is constructed by a special electric tool. Drilling, tapping, fixing and locking are completed in one time. Self-tapping screws are mainly used for the connection and fixing of some thinner plates, such as the connection of color steel plates and color steel plates, the connection of color steel plates and purlins, wall beams, etc. The penetration capacity is generally not more than 6mm, and the maximum is not more than 12mm. Self-tapping screws are often exposed outdoors, and they have strong corrosion resistance; the rubber sealing ring can ensure that the screw does not seep water and has good corrosion resistance.

According to statistics, in the case of fastener failure, the reasons for materials and heat treatment account for more than 80%. Although companies can produce according to the GB/T3098.1-2010 standard, the yield ratio, surface decarburization, microstructure, and impact toughness are often omitted in the test. Due to obvious quality risks, It causes plastic deformation or fatigue fracture under the stress of alternating loads, and such items are closely related to the heat treatment process, which means that the fastener anti-brittle fracture technology is inseparable from the heat treatment.
