Nuts, like screws and bolts, are, generally, a high volume commodity. As such, the most predominant method of manufacturing them starts

What do Multi-station Formers Do?
Prior to considering the machine itself, we should first consider what consumers and manufacturers want from these machines. The answer to this question is pretty simple, consumers want quality parts, suited for the intended purpose at a reasonable price and manufacturers want to provide such parts with the most efficient processes or methods available. In other words, as parts become more complex and sophisticated they usually
become more challenging to manufacture. The manufacturer is motivated to remain competitive, and, therefore, must evolve their manufacturing capabilities to be as efficient as possible. Let us consider for example a high volume trimmed hex head part.
