Nut and Bolt Forging.

Bolt Production Process

Bolts can have many different sizes and shapes, corresponding to different specifications, but the production process is roughly the same. First, the steel wire is cold-forged into the correct shape, then heat-treated to increase strength and surface treatment to improve durability, and then packaged and shipped. However, for more precise and complex bolt designs, other process steps will be added to the production process. Depending on where the fastener is used, there are many different processes matching options to produce the correct bolt.
