Why hot forged:

1.     the strength of the root the bolt head will be enhanced after a secondary heating. Therefore it is not easy to break.

      Cold forged bolt head material organization is relatively loose, and strength is not as strong as hot forged bolt. 

      So, for titanium wheel bolt, titanium lug bolt we suggest hot foged parts first!

2.      hot forged bolt hex socket and torx wrench is not easy slipped.
