I have a nils 6″ with extension. Even though I tighten the wingnuts before each use, I still have them disappear down the hole. Does anyone have suggestions for a different bolt/nut system to replace the wingnuts? I contacted Nils, but they do not reply. I appreciate any suggestions.

Also, I really like this auger and use it for both ice fishing and when I’m obtaining water quality studies for work…so it gets lots of use.
