The Raumer Hang Fix expansion bolts have gone through a design phase focused on creating a technology which ensures expansion on an increased number of surfaces. Attention: On particularly soft rocks (such as sandstone) all expansion bolts are not recommended due to the unreliable nature of the supporting material. In these circumstances we recommend the use of fixed resin anchors (epoxy glue resin) or Multi-Monti screw anchors.
