Concrete Screwbolt / Thunderbolts

Our Concrete Screwbolts, also known as Thunderbolts, offer a strong, stress-free anchoring solution for solid substrates such as concrete, brick, and block. These heavy-duty fixings cut their own thread during installation, eliminating the need for plugs, expansion, or resin systems.

  • Thread Sizes:
    M8 and M8/M10 dual-thread variants available

  • Available Brands:

    • Fischer – Known for precision and performance in concrete fixings

  • Applications:
    Ideal for bracketry, base plates, support frameworks, and threaded rod anchoring. These screws provide a secure hold without causing expansion stress, making them suitable for edge fixing and reduced embedment depths.

The Concrete Screwbolt range is trusted by installers for its quick installation, reusability in some applications, and high load-bearing capability.
