There is such a thing as an "AMA Safety nut (which is essentially a large "acorn" nut) But its only required for certain types of competition.

Although I have searched the AMA site high and low, and looked at other doucments, I can not find an "AMA Safety nut". I did find AMA shirts, AMA cups, AMA pins and many other items.
At this point, I think the only thing "AMA Safety nut" refers to is you... and then, only in your dreams.
So far, your posts are without merit on the subject of spinners. Do the research and try again.
