Left-hand full-thread bolt
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.
Compared with other bolts, it can be installed using ordinary foreign drilling rigs, which saves installation costs.
Anto left-handed full-threaded anchor rod, the threads are distributed throughout the rod body, increasing the moving length of the nut, if the anchor rod support is loose in the later stage, tighten the nut, and the anchor rod restores the support force.
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.
