TAS-TWA expansion anchor
This anchor has a rod with an outer thread and an anchor clip at the end. The conical shape of the end of the rod enables the clip to expand and be fixed by the force exerted and the friction produced when threading. Likewise, the clip’s shape prevents rotation and chipping. It is very important to follow the tightening torque indicated on the technical data sheets.
