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 tested method for metals and wood to broader selection of materials.
A truly versatile anchor, the concrete anchor bolt 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.
M6 - Use 6mm Drill Bit
