Abstract
An attachment for monitoring a nut of a screw connection for crack formation, deformation, and/or breakage includes a socket portion which is attached to the outer circumference of the nut and has a conductor which is interrupted in the case of a deformation, crack, or breakage of the nut. The conductor is embedded in at least one material. The attachment is produced by injection molding with the conductor embedded within the socket portion. The monitoring attachment is particularly useful for operating a shutoff device for a wind generator in the event of failure of a nut which secures a turbine blade to the generator hub.
