A picture says more than a thousand words. These flanges have the worst quality control I have ever seen. Whole package of 20pcs same as the picture. By the way. 3 levels. Orange indicates the surface is flat. Yellow color indicates that the pipe is already OK. Then black level. Do you see that bubble? Yes. The threads of these flanges are curved. The bases are crooked. Everything I put in is at a 5-10 degree angle. Many [18 of 20] flanges are also deformed. I was planning to use them for the table and legs. You are completely useless. They will be returned and I will find a company that understands the quality control of their products.
