Expansion Wedge Anchors

The installation of wedge anchors is easy and straightforward, being true to size (ie. M8, M10, etc) means the bolt can pass through the pre-drilled fixture into the hole. The load is secured once the nut and washer is tightened expanding the clip against the holes surface. In Australia this method is sometimes referred to as through or true bolt.

Our range of expansion wedge anchors are commonly specified where critical fixings are required, assessed independently under ETA requirements. Wedge anchors must meet specified embedment depths and the required torque values on installation. European Technical Assessment (ETA) reports can be used to design wedge anchors in accordance with SA TS 101:2015, as referenced in the National Construction Code (NCC) 2016.
