The function of hexagonal nut is to cooperate with bolt to achieve the purpose of fastening. Usually, in order to improve the service life of the hexagonal head hex nut, hot dip galvanized plating is the first choice for the hexagonal nut.
Of course, the main reason for H.D.G. hexagon nut is because its cost is low, simple and does not take too much time, but can achieve very good results.
Hexagon nuts with hot dipped galvanized plating have good reliability. The galvanized layer on the surface and steel are metallurgically bonded, they will form one part of the steel surface after the combination, therefore the durability of coating is more reliable. After investigation, it has been shown that in different environments, the anti-rust effect of galvanized coating is also different. In the suburban environment, the standard anti-rust effect of hot-dip galvanizing does not need to be repaired for about 50 years; in the urban or offshore environment, the standard anti-rust effect of hot-dip galvanizing can be maintained for about twenty years without repair.
