M12 X 100mm Thunderbolt The one and only Thunderbolt™ is the original self-tapping anchor with the power to be used on a whole range of construction materials, including concrete, stone, brick and block. The threaded anchor and self-tapping action allows for safe anchorage, with the substrate becoming the nut to the bolt – applying a tried and testedmethod for metals and wood to a broader selection of materials. A truly versatile anchor, the Thunderbolt™ can be installed nearer to edges and closer together at varying embedment depths, providing a stress-free fixing. Installation is quick and easy, making it the ideal general purpose anchor, even on temporary jobs as it’s completely removable. Using standard sized drill bits, the Thunderbolt™ is the cost effective fix for any job.
