Cold heading wire is mainly used for various kinds of fasteners and pins for construction & automotive use as well as precision disc use.

▎Features

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.

If required by customers, we can coat the wire with a special thin film which provides excellent lubrication for cold heading and also provides excellent lubrication for cold heading and also provides threadability including forward & backward browing, longer tool life with less clogging and easier cleaning.

  • High formability
  • Low working stress
  • Excellent surface quality
  • Most proper hardenability and low tool wearing
  • Superior low magnetism after heading & threading
