Zinc-plated steel anchor with hexagonal screw for structural fixings. Time-saving through-type installation. When tightening, the cone is pulled into the expansion sleeve and expands it against the hole wall. The recesses act as a crumple zone to take the torque slippage, pulling towards the anchoring base. Ideal for fastening fixings that are not relevant in safety terms such as consoles, handrails or cable trays. Suitable for most brick.
