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.
Features (advantages) of Left-handed Full Thread Steel Bolt:
1. High strength, full-thread full-length equal strength, which is 40% higher than the load-bearing capacity of the same specification anchor rod;
2. Reasonable structure, large pre-tightening force, expand the use range of anchor rods, and can realize end anchors, lengthened anchors and full anchors;
3. It can automatically adjust the force direction, increase the binding force on the surrounding rock, and realize mechanized and fast installation;
4. It is used for high-strength support of large deformation roadways in high ground pressure mines, and can also be used for high-strength, permanent roadway support of various projects such as railways, hydropower, etc.
