Good quality
They are the perfect size for what I needed them for! The holes at the bottom of my washing basket had gotten bigger over the years and the wheels started falling off. I was able to use one of these of each side of the base and now it is as good as new and the wheels don't fall off any more

Good
Building up a small stock for hobby projects. The washers are well made and finished and will be used on outside applications in the main as I wanted a bit of stainless steel quality to stop the rust. Cant see any reason why they wont work.
