Thunderbolt Screws

Countersunk Concrete Screw - 10mm Ø

The ideal fixing for heavy duty anchoring into brick, stone, wood concrete and concrete block. 

The Thunderbolt screw is an extremely versatile anchor screw that performs well in a wide variety of building materials including brick, stone, wood, concrete and concrete block. 

You no longer need the old fashioned method such as through bolts, shield, sleeve and drop-in anchors. Thunderbolt screws make anchoring a much more efficient  process, greatly increasing the speed of installation.

Key Features
  • High-Low parallel threads for ease of insertion and high pull-out values
  • Removable & adjustable non-expansion through fixing

  • Countersunk head gives a discreet finish into pre-countersunk holes
All steel, non-flammable fixing conforming to BS 7671 standard's 18th edition, which requires wiring systems to be supported by materials which are unlikely to prematurely collapse in the event of a fire.
