The advantage of using a square nut is that there’s more contact with the surface you’re fastening into and they’re also less likely to lose their shape after being tightened or loosened off multiple times.

Maintenance is a very important task when it comes to safety equipment and should be carried out regularly.  Make sure you’re prepared and buy the spares you need for your mask now.
