Why are lock nuts more popular than ordinary nuts? The lock nut has strong abrasion and shear resistance. The lock nut is self-locking by the friction between the nut and the bolt.
The lock nut is loved by all walks of life, but this does not mean that the lock nut is popular when it first appeared, but the product becomes excellent through continuous evolution and upgrade, and thus it is widely used.
Technology is the main source of promoting product development. It is also important that humans have a higher demand for products.
