Technical features
 Adopting the advanced production line crack detecting, quenching, the continuous overall tempering and sand blasting processes to achieve higher mechanical strength ability with overall good performance.

1. The thread is cut by the special-purpose numerical control lathe which keeps the rod body still when cutting the threads. The special process ensures a high precision of thread with better reliability and life-span.
2. Coupling phosphor or copper coated to achieve good wearing-resistance ability and anti-thread gluing ability.
