What is triangle tooth self - tapping screw
Triangular teeth, self-tapping Screws, Thread Rolling Tapping Screws), also known as Type TT is developed based on the principle of forming tap. The screw has a specially designed thread and tail that allows the screw to roll itself into a mating female thread under intermittent pressure. At the same time, the material around the hole can more easily fill the space of self-tapping screw thread and tooth bottom, because its friction force is smaller than that of the screw forming self-tapping screw, so it can be used in thicker materials, the torque required for rotation is better controlled, and the combined strength is higher. The engineering standard definition of screw roll self tapping screw is higher and more explicit in terms of material, heat treatment and strength than that of molding or cutting self tapping screw, making screw roll self tapping screw a real "construction" buckle.
What is triangle tooth self - tapping lock screw
It is a kind of tapping screw, its thread is a common thread with arc triangle section, the thread surface also has higher hardness, so in the connection, the screw can be in the bottom hole of the connected piece tapping out the internal thread, so as to form a connection. This screw is characterized by low torque and high locking performance.
After we understand, is sure to want to know it has what great benefits, below small make up with you to understand...
1. The hardness of some products can be higher, such as iron plate. Triangle tooth screw just use his self - attack property, better into the product.
2. It does not need to be like a mechanical screw, it needs to be equipped with a nut. This helps to save customers' costs.
Compared with ordinary dental screws, triangular teeth can reduce the resistance in the process of locking. It relies on three points to attack the workpiece. During the locking process, there will be a thermal effect, which will prevent the screw from going out of place after cooling. The tooth hill Angle machine tooth is generally 60 degrees, the thread strength is high, the lock pay force is small, the production is relatively easy, also has 55 degrees tooth, the wechsler tooth. The thread has the function of locking, transferring and sealing. Like square thread, ladder thread, generally only transfer. The difference between triangle and square is the difference between triangular teeth. It is explained in mechanics and geometry that triangle is more stable than quadrilateral.
