Summary

The Thunderbolt is the original and best-selling general-purpose all-metal masonry anchor, designed for use across a wide range of construction materials including concrete, brick, blockwork, and stone. This M12 x 75mm variant features a hexagon head and a yellow zinc-plated (ZYP) finish for corrosion resistance. It is the preferred choice for trade professionals requiring a fast, reliable, and removable structural fixing.

Features

• One-piece, non-expansion anchor - requires no wall plug or resin for installation.
• Unique self-tapping thread engages directly with the substrate, which acts as the nut to the bolt.
• Hexagon head provides a secure drive point for installation with a standard spanner or socket.
• Suitable for close-to-edge applications with minimal risk of substrate cracking or stress fractures.
• Fixes along the entire thread length, enabling use in hollow sections as well as solid substrates.
• Easily removable, making it ideal for temporary fixings or maintenance applications.
• Yellow zinc-plated (ZYP) finish provides reliable corrosion resistance for general construction environments.
• No marking out required - drill through the fixture directly and wind in the anchor.
