Iccons Thunderbolt PRO Hex Head Zinc screw for strong, versatile anchoring.
Description
The Iccons Thunderbolt PRO Hex Head – Zinc is a high-tensile, self-tapping concrete and masonry screw anchor designed for professional and residential construction applications. Its premium zinc finish provides excellent corrosion resistance, making it ideal for a wide range of indoor and protected outdoor environments. Engineered for efficiency, installation is quick and simple: drill, clean the hole, and screw in the anchor with ease.
AS5216:2021 compliant, with ETA assessments for cracked concrete, fire performance, and seismic ratings, the Thunderbolt PRO achieves maximum load performance while generating low expansion forces. Unlike mechanical expansion anchors, it keys into the base material across the entire hole depth and diameter, reducing stress on concrete and allowing close anchor spacing and near-edge installations. Featuring 10 sharp thread-forming teeth, it provides a secure and reliable connection in concrete, block, brick, timber, marble, and stone.
Completely removable and residue-free, the Iccons Thunderbolt PRO Hex Head – Zinc is ideal for temporary or permanent installations. Its one-piece, fast, and cost-effective design makes it a versatile and reliable fixing solution for commercial, residential, and infrastructure projects.
