Why use trilobular thread screws？

Compared with ordinary self tapping screws, Trilobular thread screws can reduce resistance in the process of fastening. Because the Trilobular thread screws is fastened to the machined part by three points, a thermal effect will be generated in the process of fastening, which will play the role of loosening the imitation stop screw after cooling. Trilobular thread is generally 60 degrees, with high thread strength and small locking force, which is easy to produce.
