Benefits & Features
Right-handed threaded steel rock bolts, also known as right-handed rock bolts or mine-use right-handed rock bolts, are mainly used in tunnel and surrounding rock reinforcement fields of coal mines, railways, hydropower, etc. This product is made of right-handed precision-rolled threaded steel bars and has a continuous full-thread structure. It can be combined with rock bolt support plates and nuts to form a three-way force-bearing system.
Product features:
(1) The structure is reasonable. The strength of the rock bolt is equal throughout the thread and the length, which solves the shortcomings of the low strength of the anti-torsion rock bolt thread and the flattened part.
(2) The bearing capacity is more than 40% higher than that of the same specification anti-torsion rock bolts.
(3) The operation is simple, the price is low, and it is widely used in various tunnel supports of coal mines, railways, and hydropower projects. Product advantages:
(1) The anchoring end and the tightening end do not require machining.
(2) The full-length strength is equal, and the material utilization rate is high;
(3) The anchoring force is large;
(4) It is equipped with a prestressed pad, and the installation quality is easy to control.
(5) The installation speed is fast, and other features. It is a new type of rock bolt that saves materials, reduces labor, and has the same strength. The right-handed threaded steel rock bolt has broad application prospects.
