Concrete Fixing Set M8×90 A2 (2 pcs)

Concrete Fixing Set M8×90 A2 (2 pcs) is a set of two stainless steel wedge anchors designed for securing metal brackets, railing components and other structures to concrete substrates. The M8×90 mm anchors are manufactured from A2 / AISI 304 stainless steel and feature a mechanical wedge expansion mechanism. When the nuts are tightened, the expansion sleeves engage with the concrete to create a secure mechanical connection.

This concrete fixing set is particularly suitable for installing metal components with two mounting holes. The set includes two M8×90 mm wedge anchors, complete with nuts and washers, providing a convenient fastening solution without purchasing individual components separately. A2 stainless steel offers good corrosion resistance, making the anchors suitable for indoor installations and normal outdoor environments.

Installation

1. Mark the fixing positions. Position the metal bracket or mounting plate against the concrete surface and mark both mounting hole locations.

2. Drill the holes. Use a hammer drill with a Ø8 mm concrete drill bit to drill two 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 two M8×90 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 component. 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. Before installation, verify the concrete condition, expected loads, minimum edge distances, anchor spacing and the manufacturer's installation requirements. A2 / AISI 304 stainless steel is suitable for many standard indoor and outdoor environments. However, coastal areas and other locations exposed to higher chloride concentrations may require fasteners with greater corrosion resistance, such as A4 / AISI 316 stainless steel.
