Any auto parts joint will sell you a tube of locktite. You want the blue variety.  It's also available in red, which takes heat should you ever want to undo things.  Confusingly, they both may come in a red bottle.  (There are other brands, but they use the same color coding scheme)

Use is simple, one or two drops applied to the threads, then install and tighten the nut as normal.   Should there be reason to undo them, it will just take a sharp knock on the end of the wrench to break it loose.

Thanks! The staple bolt on the 8 needs something more (I think a new washer or something), it’s always a little loose, but never actually loosens…

Many thanks!

The staple bolt is the one that sticks up through the top of the bell and has the two nuts on the top; these have all been fairly good lately, but in years past they have come loose…)
