Are nuts cast?

Nuts can be cast, but in general, nuts will not be cast. Nut casting has many defects, low strength grade and poor machinability, and its advantage is wear resistance. The general nut processing methods are small-size cold heading and large-size red punching. You'd better check the relevant information yourself. Everything I got online was fake. If you don't pretend to understand and answer casually, it will mislead you directly and even hurt you.
