Application prospect: Left-handed anchor rod, also known as threaded steel resin bolt without longitudinal reinforcement. Compared to right-handed bolts, left-handed bolts weigh more than meters and have fine threads on the top of the rod body. The strength of the threaded section is greater than that of the rod body, and the threaded section has outstanding bending and shear resistance performance. It is a new type of coal mine roadway support anchor rod. This bolt has high strength, a reasonable structure, and a large pre tightening force.
