Tiger Bolt ^®

General Features

• The Tiger Bolt is manufactured from a high strength tube which has a rope style universal thread profile 8.05mm pitch along its entire length. A 200mm length of thread bar has been swaged into one end, with the other end of the tube crimped. The bolt is provided with an OZ nut, collar and a destructible cardboard resin holder, which contains a "Duo Speed" resin capsule.
• The thread bar tube swage strength is equal to the strength of the tube.
• Supplied in standard version as a passive ground support element.
• A pretensionable version is available on request with the following features.
• The thread bar provides for:
  1. Variation in the drilled length of the hole (both over drilled & under drilled)
  2. Rock confinenment by preloaded plate
  3. Pre-tension in the bolt
  4. A meshing / hanging brackets / pulling test
  5. A drive nut system ensures quality control of the bolt installation
• The rope style universal thread profile on the tube assists in resin mixing and provides superior load transfer characteristics.
• The specially designed top crimp assists in resin mixing.
• The cardboard resin holder with plastic stopper ensures that the holder does not enter the drilled hole and therefore does not interfere with the encapsulation of the bolt ensuring good load transfer characteristics between the tube and resin. The cardboard holder is biodegradable.
• The specially designed collar allows for correct alignment with dome plates.
• Single pass installation.
• Two speed resin allows for bolt pre-tension.
• Bolt can be galvanised (both exterior and internal) for corrosion protection. Tube is fully sealed when fully encapsulated.
• The Tiger Bolt is patent pending
