The Hexagon Flange Nut Sleeve Anchor (ZYP) is a versatile, torque‑controlled anchor designed for secure fixing into non‑cracked concrete, dense blocks, solid brick, and natural stone. Its thin‑walled expansion sleeve and diagonal slot design create a strong clamping force, making it ideal for light‑to‑medium‑duty applications. Pre‑assembled for fast installation, it delivers dependable performance across a wide range of on‑site fixing tasks.

How it works

When the nut is tightened, the anchor sleeve expands inside the hole. The diagonal slot allows the sleeve to collapse and grip the substrate, creating a strong clamping force between the fixture and the base material. This controlled expansion ensures a secure, reliable hold.

Product Description

Hexagon Flange Nut Sleeve Anchors ZYP

Reliable Fixing for Concrete and Masonry Applications

The Hexagon Flange Nut Sleeve Anchor is designed for installers who need a dependable fixing solution across a range of masonry materials. Its thin‑walled sleeve makes it suitable for substrates such as non‑cracked concrete, dense concrete blocks, solid brickwork, and even some natural stone. The zinc and yellow passivated finish provides corrosion resistance for indoor and sheltered outdoor environments, making it a versatile choice for general construction, maintenance, and installation work.

Fast, Simple, and Secure Through‑Fixing

This anchor is supplied pre‑assembled, allowing installers to position the fixture, drill through, and anchor in one continuous process. The torque‑controlled expansion mechanism ensures consistent performance, once the nut is tightened, the sleeve expands evenly to lock the anchor in place. The diagonal slot in the sleeve is engineered to collapse under torque, generating a strong clamping force that secures the fixture tightly against the substrate. This makes it ideal for plates, brackets, rails, racking, and other light‑to‑medium‑duty fixings.

Built for Practical, Everyday On‑Site Use

Whether you're installing handrails, signage, stadium seating, or general metalwork, this sleeve anchor delivers reliable holding power with minimal installation time. The hexagon flange nut provides a secure tightening surface, while the steel body ensures long‑term durability. Its compatibility with multiple base materials makes it a go‑to anchor for tradespeople who need a simple, effective fixing that performs consistently across different job types.
