I have acquired three different brands of ER20 nuts in the past few weeks. I just received these from Maritool and thought some of you may be interested.

I will use only balanced nuts on a high speed spindle and I want quality that I can trust.

Maritool advised, “Currently we balance our nuts by uneven depths of outer wrench flats. Or by internal details near the cam. All our nuts are balanced.”
