I changed to two-eared spinners some months ago, after struggling to remove the original hex nuts without resorting to a hair dryer!
They go on and come off easily, as Robbie says.
They also look soooo much better !

Except now I have four redundant 'Morgan' hex nuts, and I don't smoke, so no use as ash trays around the house.

Is there any other decadent use you can put them to? confused2
