1. Anchor head: The barbs on the anchor head locate the anchor rod in the drilled hole and ensure that the rod is well centered.
2. Anchor rod body: an important building block in the assembly, which plays a major role in anchoring and support.
3. Slurry stopper: maintain the slurry pressure during the grouting process, so that the slurry is fully filled into the gap of the surrounding rock.
4. Plate: to bear the greater stress of the surrounding rock. 5. Nut: to concentrate the stress of the surrounding rock on the plate
