Cold heading process is most suitable for the production of bolts, screws, nuts, rivets, pins and other standard fasteners.

1) The tensile strength of cold heading is about 10% higher than that of cutting, and some can even be increased by 20%. This is because the metal fiber of cold heading processing products will not be cut off, the internal structure of the metal is compacted, and the presence of the phenomenon of work hardening, so the mechanical properties of the metal are improved.

2) Cold heading technology can improve material utilization rate. The material utilization rate of cold heading nut can also reach about 80%, while the material utilization rate of cutting nut is only 54%.

3) Cold heading can greatly increase productivity. Such as cold heading nut compared with the original cutting process, productivity about 25 ~ 30 times.

4) Cold heading technology can improve the product surface finish and ensure the product accuracy. General finish up to V5, special requirements up to V6.
