Thunderbolt Pro – Hex Head

Product Code


ICCONS Thunderbolt®Pro Hex Head is the latest high tensile screw-in, self-tapping concrete and masonry anchor for use in a wide range of materials used in the construction Industry. Installation is quick and easy, simply drill, clean the hole and screw in the anchor. If you are after the best general purpose Screw Bolt in the business, ICCONS Thunderbolt Pro Hex Head is your anchor.

ICCONS Thunderbolt®Pro achieves the Highest Loads while generating Low Expansion forces which can make it a great alternative to adhesive anchors. The Thunderbolt®Pro is also completely removable making it ideal for temporary applications. Unlike mechanical expansion anchors, the Thunderbolt®Pro keys into the base material for the entire depth and diameter of the hole, not just at the base of the hole. This reduces high energy forces within the concrete allowing close anchor spacing and near-to edge anchor locations. 10 sharp thread forming teeth ensure the most secure connection in hard base materials. The Thunderbolt®Pro is a truly versatile anchor, as it can be installed in whole range of base materials such as concrete, block, brick, timber, marble, and stone, just to name a few. The highly engineered design of ICCONS Thunderbolt®Pro is the result of extensive testing and provides market leading load performance. ICCONS Thunderbolt®Pro is a one piece, fast, efficient and cost effective fixing solution for any job.

  • Use the correct diameter drill bit
  • Drill a hole to the required anchor embedment depth, plus at least one anchor diameter deeper
  • DO NOT use a worn drill bit outside tolerance specification
  • Ensure the hole is drilled perpendicular to the concrete, with a maximum deviation up to 5 degrees. Failure to do so may cause anchor breakage
  • Clean dust and other materials from the hole. Use ICCONS Blow Pump for a perfect result
  • Use a torque wrench or an impact driver
  • Ensure correct clearance hole in the fixture
  • Apply pressure against the fixing
  • Rotate to engage the first thread
  • Tighten the anchor until it is firmly seated
  • When using an impact driver DO NOT overtighten! Follow the torque guidance table, failure to comply may result in anchor breakage. Refer to ICCONS TDS for further information
