Thunderbolt Pro-XTM – Countersunk Head

Product Code


ICCONS Thunderbolt Pro-XTM Countersunk Head is the latest approved 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-XTM Countersunk Head is your anchor.

ICCONS Thunderbolt Pro-XTM achieves the Highest Loads while generating low expansion forces. The Thunderbolt Pro-XTM is also completely removable making it ideal for temporary applications. Unlike mechanical expansion anchors, the Thunderbolt Pro-XTM 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. Sharp thread forming teeth ensure the most secure connection in hard base materials. The Thunderbolt Pro-XTM is a truly versatile anchor, as it can be installed in a 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-XTM is the result of extensive testing and provides market leading load performance. ICCONS Thunderbolt Pro-XTM is a one piece, fast, efficient and cost effective fixing solution for any job.
