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.

The nut I was hoping to buy isn't available in 1mm pitch. The std course thread is 1.5mm pitch. I have a local fastener house looking for non-Nyloc nuts. Let ya know.
