Quick and easy assembly. Neoprene rivet body, electrically non-conductive. Temperature-resistant from -30°C to +80°C. Oil and corrosion resistant. Example of use: Drill or blank mounting hole. Stick in ISO box nut. Turn the screw with the part you want to attach into the ISO box nut with moderate force. By turning the screw the rivet body bellies out and forms a safe and tight closing head. In the case of a blind bore the elastic rivet body fixes itself by frictional connection.
