| Introduction |
| Cold heading wire is mainly used for various kinds of fasteners and pins for construction & automotive use as well as precision disc use. It has excellent corrosion resistance and mechanical properties depending on the grades, In order to obtain good-shaped upsetting and threading,it is very essential to select the most suitable grades with highest quality. |
