hi ..i have never seen a wing nut with the plastic stop material in them.. wing nuts are meant to be put on and taken off easily , by hand. I seriously doubt wing nuts with plastic stops in them exist ...better to go the washer/lock washer/ wing nut route. the elastic stop nuts are meant to be put on and not removed and not come loose under vibration, such as in machinery and aeronautics.
