Abstract
The invention provides a lightning receptor arrangement () for a wind turbine blade () comprising at least a self-threading screw () having a head () and a threaded shaft () as a the external metallic receptor element for receiving a lightning strike in one side of the wind turbine blade () and an internal element comprising an electrically conductive block () configured with at least an unthreaded hole () for cooperating with said threaded shaft () and connected to a down conductor () of a grounding arrangement. The internal element is joined to at least a shell () of the wind turbine blade () with an adhesive force capable of withstanding the torque applied to the self-threading screw () for threading it to the unthreaded hole ().
