Concrete Fixing Set M8×80 ZN (4 pcs)

Concrete Fixing Set M8×80 ZN (4 pcs) is a set of four zinc-plated steel wedge anchors designed for securely fastening railing posts, metal brackets and various structural components to concrete substrates. The M8×80 mm anchors feature a mechanical expansion mechanism that engages with the concrete when the nuts are tightened, creating a secure mechanical connection.

This concrete fixing set is particularly suitable for installing metal structures, supports and mounting plates with four fixing holes. The package contains four wedge anchors, each supplied with a nut and washer, providing a convenient fastening solution without purchasing individual components separately. The cold zinc-plated finish (ZN) provides basic corrosion protection, making this set suitable for dry indoor environments only.

Installation

1. Mark the fixing positions. Position the mounting plate or metal component against the concrete surface and mark all four mounting hole locations.

2. Drill the holes. Use a rotary hammer drill with a Ø8 mm concrete drill bit to drill four holes at the marked positions. The drilling depth must comply with the anchor manufacturer's installation requirements. Thoroughly remove drilling dust and debris from the holes.

3. Insert the anchors. Insert the four M8×80 mm wedge anchors into the drilled holes and carefully tap them into position using a steel-headed hammer. Keep the nuts threaded onto the anchors during tapping to help protect the threads.

4. Secure the structure. Position the mounting plate over the anchors, install the washers and nuts, and tighten them using a suitable wrench. Apply the tightening torque specified by the anchor manufacturer. Tightening activates the expansion mechanism, securing the anchors inside the concrete.

Important: This fixing set is intended for installation into suitable concrete substrates in dry indoor environments only. Before installation, verify the concrete condition, expected loads, minimum edge distances, anchor spacing and the manufacturer's installation requirements. The cold zinc-plated finish is not intended for prolonged exposure to outdoor or damp conditions. For such applications, select fasteners with an appropriate corrosion resistance rating.
