AOP Precast produced fixing socket with angular end and nail plate transfer forces directly into the concrete without additional reinforcing steels. Forces are transferred via the angular end. No additional reinforcement is necessary.The fixing socket with angular end and nail plate did not need plastic nail plate. The angular end anchors itself into the concrete by means of form closure. The required concrete compressive strength is at least 25 N/mm². We recommend fixing socket with angular end only for fixings, for which a general technical approval is not necessary.
