  • Bolt and process for producing a protective layer on a bolt
    Publication number: 20040208726
    Abstract: The invention relates to a process for producing a protective layer on a bolt, in which an aluminum-containing high-temperature lacquer is first of all applied to the bolt and then cured and stoved at a defined stoving temperature. The screw thread is additionally lubricated prior to installation of the bolt. This process reduces oxidation and ultimately reduces seizing of the screw connection.
