Prime advantages of the AT - Power Set Self-drilling Friction Bolt

  • Simultaneous drilling and installation
  • Installation with standard drilling machines
  • Immediate load-bearing capacity after installation
  • Direct load transfer over the entire bolt length
  • Ability to maintain load-bearing capacity even when undergoing large deformations
  • High shear resistance (shear strength > tensile strength)
  • Non-sensitive to vibrations and blasting operations
  • Secure, easy and time-optimized installation procedure
  • Assured bolt installation even in the case of unstable boreholes
  • No injection or grouting necessary
  • Ergonomic and safety-related advantages for the workforce
