Hexagon Flange Nut Sleeve Anchors A4 Stainless Steel

Overview

A4‑316 stainless steel sleeve anchor with torque‑controlled expansion for secure, corrosion‑resistant fixings in concrete, brick, block, stone and perforated masonry.

How it works

The diagonal slot allows the sleeve to collapse and expand evenly when tightened. This creates a strong clamping force inside the substrate. The flange nut spreads load across the fixture for a secure hold.

Outdoor fixings can be a real headache, especially when you’re working near the coast or in exposed environments. Standard anchors can rust, weaken or seize over time, leaving you with loose fittings or costly rework. That’s why choosing the right material matters.

Hexagon Flange Nut Sleeve Anchors in A4 Stainless Steel are built to solve that problem. Made from A4‑316 marine‑grade stainless steel, they’re designed to withstand rain, salt, moisture and long‑term exposure without corroding. You get a fixing that stays strong, secure and reliable year after year.

The torque‑controlled expansion gives you consistent performance across concrete, stone, brickwork, perforated bricks and dense concrete blocks. The sleeve collapses smoothly, gripping the substrate and pulling the fixture tight. It’s simple, dependable and ideal for light to medium‑duty applications.

Because they’re pre‑assembled, installation is quick and straightforward. Just drill, insert, tighten and move on, perfect when you’re fitting multiple anchors or working at height.

Whether you’re installing handrails, plates, racking, stadium seating or signage, these stainless steel anchors give you the durability and confidence you need for external and marine environments.
