This article introduces four common surface treatments for bolts: coating, hot-dip galvanizing, electroplating, and Dacro. These methods can improve the corrosion resistance and appearance of bolts. Coating and electroplating can make the surface of the bolt smoother and more beautiful, but they are not durable and are easily scratched; hot-dip galvanizing and Dacro can enhance the anti-corrosion ability, but the surface is not beautiful enough. Now there is a hexavalent chromium-free formula for Dacro, ʻoi aku ka maikaʻi o ke kaiapuni. This article briefly introduces the advantages and disadvantages of each treatment method, as well as their importance.

This article discusses the application and difference of hot forging and cold heading processes in fastener products. ʻO ke poʻomanaʻo anu i hoʻohana piha ʻia, resulting in a low defect rate, but the strength of products produced is limited to a maximum of 10.9 and requires heat treatment to reach higher strength levels. Cold heading machines have a basic minimum order quantity of 1 tona. On the other hand, hot forging involves manual labor and can produce products with up to 12.9 ikaika. Eia naʻe, the labor cost is high, and the hot forging process is more expensive than cold heading in mass production. The article concludes that the hot forging process can be used for small inquiry quantities and low appearance requirements.
