Hey guys, I need some help here. I bought a pack of the chicken waterer cups and they did not come with a nut or washer to go on the back side. I use them in a 5 gallon bucket and like to be able to secure them from the inside of the bucket with a nut and washer, but these did not come with any. Does anyone know what I can use? I have been looking for something that would work and I cant find anything with the same thread size.
