The following are the features of the mainly popularized high performance self drilling anchor bolts:

① They are made of 20MnSi sinistral thread steel without longitudinal reinforcements.② New processing technique with low loss of strength are applied for their external thread part. 

The size and strength of accessories  such as nuts, plates and steel tapes are appropriate.

③ Mechanical installation is applied.

④ There are striking signs to show quality of construction directly.

Since the year 2011,Sinorock set up its first own self drilling anchor bolt factory, and gradually extended to designing and producing rock drilling tools. And later it constructed the other factory by in Changzhou. In addition, this company always keeps an open mind and cooperates with other factories from both China and outsea countries, to get complementary advantages in both products and markets. And through such strong enterprises’ combination, it is able to offer better and full range products and services for all kind of drilling need for mining, construction,water well drilling and so on.

To be a reliable bolt manufacturer, Sinorock is making effects to produce quality self drilling anchor system.Sinorock has researched and developed efficient production line of self drilling anchor bolt after years’ effort. This production line can realize several advanced functions such as control the temperature, store data automatically during rolling.For provide quality self drilling anchor system.
