Summary:Overvoltage arresters are used to protect against overvoltages in electrical energy transmission systems. An overvoltage arrester has a discharge column which extends along a longitudinal axis and is clamped in between end fittings by a plurality of tensile elements which radially surround the discharge column and are secured in the end fittings. At least one of the end fittings has a first thread for attaching a connecting bolt. Furthermore, the end fitting has a fitting body with a second thread for receiving a pressure screw for generating an axial force on the discharge column. Accordingly the first and second threads overlap along an axial section.
