The triangular tooth screw is also called the triangular tooth self-tapping locking screw, or the triangular tooth self-locking screw. Or triangular tooth screws. It means that the tail of the self-tapping screw is triangular, and the thread of the tooth is triangular. It belongs to a special class of self-tapping screws. We can first understand the basic knowledge of self-tapping screws.
Function：
Compared with ordinary tooth screws, triangular teeth can reduce the resistance during the locking process. It uses three points to tap the workpiece. There will be a thermal effect during the locking process. After cooling, it will prevent the screw from moving. . Triangular mechanical teeth are generally 60 degrees, high thread strength, low locking force, easy production, and 55-degree teeth, Webster teeth. Threads are divided into locking, transmission, and sealing functions, such as square threads and ladder threads, which are generally transmission functions. The difference between triangles and squares is the difference between triangular teeth. It is explained in mechanics and geometry that triangles are more stable than quadrangles.
