The difference of electric galvanization and hot dip galvanization (HDG)
Steel rusts easily in air, water or soil, and even breaks down completely. Every year, the loss of steel caused by corrosion accounts for about 1/10 of the total steel output. On the other hand, in order to make the surface of steel products and parts have a certain special function and give them a decorative appearance on the surface, it is generally treated by electric galvanizing.09

Choice of coarse and fine thread
How fine a thread is called a fine thread? Let's define it this way. The so-called coarse thread can be defined as a standard thread; While the fine thread is relative to the coarse tooth, in the same nominal diameter, the number of teeth per inch is different, that is, the pitch is different, the coarse tooth pitch is large, and the fine tooth pitch is small. In other words, for both sizes 1/2 to 13 and 1/2 to 20, the former is coarse and the latter is fine. So it's 1/2 minus 13UNC and 1/2 minus 20UNF.
