Self-drilling anchor bolts provide effective ground stabilization solutions for challenging geological conditions including sand, gravel, silt, clay, and soft to medium fractured rock formations. These specialized bolts combine drilling and anchoring functions in a single operation.

• Hollow anchor bolt with integrated drilling capability
• Anchor nut and plate for secure fastening
• Anchor coupler for extension applications
• Drill bit optimized for various ground conditions
• Centralizer for proper grout distribution

The system operates by drilling directly into unstable soil or loose rock formations using the hollow bar and drill bit assembly. Following drilling completion, grout is injected through the hollow bar to fill both the internal cavity and surrounding ground, creating a robust anchoring solution.
