Right-handed rock bolts are made of right or left handed precision-rolled rebar, with continuous threads and full-length nuts. They are usually used in conjunction with anchor nuts and roadway support .

Under normal circumstances, right-handed rock bolts have the characteristics of reasonable structure and full strength of the full thread of the rock bolt, which to some extent solves the problems of anti-twist rock bolts and low strength at the flat. Right-handed rock bolts have nearly 40% higher load capacity than anti-twist anchors of the same specifications. They are simple to operate and inexpensive, and they are widely used in mines, railways, hydropower and other projects for roadway support.

Several essential factors that make up the right-handed rock bolt :

1. A rod with higher tensile strength than rock and soil;

2. One end of the rod can be in close contact with the rock and soil to form friction (or adhesion) resistance;

3. The other end of the rod located outside the rock and soil can form radial resistance to the rock and soil.
About the use of right-handed rock bolt:

1. Determine the anchor hole position according to the design requirements and use a drill to drill holes;

2. Blow out the rock powder in the hole with compressed air;

3. The diameter of the drill hole must be 6-12mm larger than the diameter of the right-handed rock bolt;

4. Use the anchor rod to send the anchoring agent to the bottom of the hole, start the stirring device to stir, and strictly control the stirring time according to the requirements of the resin anchor bolt capsule;

5. After the waiting time is reached, put on the anchor plate and tighten the nut.
