Left-handed full-thread bolts are 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.ANTO left-handed full-thread bolt is made of high-strength HRB500 or HRB600, which can provide high load-bearing capacity to protect mine safety.
The one-way left-handed rebar bolt without longitudinal reinforcement can be used in all kinds of mines and underground projects,and is especially suitable for the support of coal tunnels with wire mesh. It has achieved good technical and economic effects. The structural features of the anchor rod: the full length of the body has a rolled continuous thread, and the full length is of equal strength; the fastening end is provided with a prestressed gasket and a ball nut. It is superior to the bolt processed by round steel, and is a new type of bolt with material saving, labor saving and equal strength.
