Does anyone know what thread the rocker studs are? My rocker arms come loose frequently too. I just purchased some locking nuts for a machine at work that the Nyloc nuts were loosening often. These nuts have a couple deformed threads and hold very well. They don't damage the screw thread either. If I can find the new nut for the 1.9, I'll let you know.
