Hex Head Masonry Anchors, Zinc Yellow

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. A truly versatile anchor, the Thunderbolt™ is also available in Galvanised format, giving it the added power to last longer in environments with a corrosive atmosphere, such as coastal, marine and industrial locations.  
 
The threaded anchor and self-tapping action allows for safe anchorage, with the substrate becoming the nut to the bolt. 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.
