For people who use hexagonal bolts, anti-corrosion treatment is an important part. According to different corrosion conditions, different treatment methods can be used. The following briefly introduces several anti-corrosion treatment methods for hexagonal bolts.

The lock nut is easy to install and can be reused. Precision machinery self-locking nuts with copper pins are widely used in machine tools, engineering and other industries.

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.

Flange nuts, nuts with washers, tooth nuts, hexagonal flange nuts, flange nuts, etc., are mostly used in pipe connections or workpieces that need to increase the nut contact surface.

The size of flange nut and general hex nut is basically the same as the thread specification, but compared to hex nut, it is a one-piece gasket and nut, and there are anti-skid teeth underneat

Generally, nuts with hexagonal flanges are collectively referred to as flange nuts. Due to the good performance of flange nuts, their applications are very common.
