Wedge Anchor – Galvanised

Golden Anchor is a stud bolt expander which in its lower section, the anchoring section, has a stainless clip that expands up on the tapered part of the bolt when tightened. The upper section is equipped with an external thread with a flange nut, i.e. a combined nut and washer. In order to avoid damage to the bolt threads when inserting, the upper section features an impact head. When the drill diameter is equal to the screw diameter contact is created between the hole wall and the clip even when Golden Anchor is knocked into the hole. When the flange nut is tightened the bolt is forced outwards, whereby the clip is forced to expand up on the tapered section. The hot dip galvanized versions of the Golden anchor are made of carbon steel inclusive of a strength grade minimum; 5.8 with stainless clips.
