All Thread Bar Bolt:
All thread bar bolt is mainly used in mines where rock formations such as coal mines are not hard enough. bolts are generally used together with anchoring agents to achieve end anchoring or full anchoring in mines.
All thread bar bolt is made of high-strength HRB500 or HRB600, which can provide high load-bearing capacity to protect mine safety.
Compared with other bolts, it can be installed using ordinary foreign drilling rigs, which saves installation costs.
Advantages of All thread bar bolt:
1. Made of high-strength material, high supporting force.
2. The threads are distributed throughout the rod, increasing the movable length of the nut.
3. Used together with anchoring agent to achieve end anchoring or full anchoring.
4. Black or hot-dip galvanized.
