There is nothing wrong with the product itself. The bolt of the small head I wanted was not quite at home center, but it was found here and it was saved. However, because it is described as stainless steel, it is natural, but it is natural, because it was black in the photo of the product, I opened it and thought that I ordered the wrong bolt. Personally I wanted black, so I would be happy if I could make it around black oxide film, but it is not a lot to use, so I do not buy it sooner or later but there are bolts that will be saved. I think that it is better to change merchandise photos.
