Or it might be that the area above and below the washer have been worn smooth and slippery. Sometimes you can get some more life out of it by bending the washer (or opening it a little) and sanding/roughening the areas of contact (increasing the grip). | |

I think that the washer may be loosening for a few reasons... in my case, I'm pretty sure that expansion and contraction from cooking was the problem (which explains why the manufacurer used a lock washer). If you replace it, it should last a while before it starts to loosen again. | |

We have a pressure cooker whose handle is fixed with a machine screw along with a washer with uneven ends as shown in your picture. It avoids us to tighten the screw completely and loosens more often. | |
