These types of nuts have a flange on one side to act as a washer. Flange nuts are often used in chainsaws because the user will not need a separate washer. They will still achieve the benefit of spreading the pressure of the connection over a larger surface area. The flange nuts also tend to stay tighter, so there is less of a risk of them becoming loose when the machine vibrates during operation. Flange nuts can last for a long time, but they may eventually need to be replaced. If they begin to corrode or they have sustained damage, they should be replaced with new nuts. In some cases, the owner might have lost one of the nuts on their machine, which will require a replacement before it can be used safely.
