Self-locking screws refer to self-tapping screws that do not need to be used in conjunction with nuts. The thread is self-tapping and the tail is pointed. When the triangular tooth self-extrusion screw is screwed into the hole on the plastic metal material, the internal thread is formed in the hole by extrusion, and a reliable locking threaded connection is formed. Triangular self-locking screw refers to triangular self-tapping screw. The tail is pointed and triangular. A line with three prisms.
Second, the characteristics of triangular self-locking screws
1. Triangle tooth self-locking screw does not need to be tapped in the hole, but can be directly screwed into the hole of drill pin, die-cutting or die-casting.
2. Triangular geometry is very effective for the formation of non-cutting internal threads, and the thread forming areas with different lengths maximize the bearing capacity of the thread surface and are easy to locate. In addition, low thread self-tapping torque, high impact resistance, thread forming without cutting self-tapping and so on are superior to other screws.
3. Tapping-free triangular self-locking screw reduces the production cost and improves the working efficiency.
4. Triangular self-locking screws have higher pre-tightening force and are more anti-loose.
5, the tightening torque can be reduced by 50%, the assembly process is simpler, and the production is easy.
6, the material flow becomes easy, and the material deformation can be reduced.
7. Triangular self-locking screws are widely used in electronics, communication, motors, vehicles, medical devices, watches, glasses, power tools, locks and other fields.
