Unifix Thunderbolt Galvanised Hex Head Masonry Anchor M16 x 150mm (Box of 10)

Summary

The Unifix Thunderbolt is the original all-metal self-tapping masonry anchor, designed to fix directly into concrete, brick, blockwork and stone without a separate sleeve or plug. The M16 x 150mm galvanised hex head variant is built for demanding environments where corrosion resistance is essential, including coastal, marine and industrial settings. Supplied in a box of 10, it is a first-choice anchor for engineers, builders, plumbers and roofing contractors.

Features

• Self-tapping anchor design cuts directly into the masonry substrate - no expansion sleeve, no plug required.
• Mechanical galvanised finish provides robust corrosion resistance for external, coastal, marine and industrial use.
• Performs reliably across a wide range of substrates including concrete, brick, concrete blocks and stone.
• No expansion stress is placed on the substrate during installation, reducing the risk of cracking near edges.
• Fully removable after installation, making it suitable for temporary structures, formwork and hoarding.
• Hex head drive allows clean, wrench-driven installation for fast, secure fixing.
• Suitable for heavy-load structural applications, carpentry installations and security fixing.
• Closer edge and spacing distances permitted compared with traditional expanding anchors.
