For Large Scale Solar Energy System made of carbon steel, the U channel nut are almost the domain nut for this project.

With U channel mounting rails being universal size, the size for nut is also suitable for almost all of the mounting channel rails.

But what more about the U channel nut?

For easier installation, it comes with a plastic wing for angle’s adjust.

And the surface of U channel nut is DACROME. From the appearance speaking, Dacrome don’t have much difference from Hot dip galvanized solar mounting bracket.

But usually solar mounting bracket’s large accessories like poles, rails, beams while in the hot dip gavalnized proccess it’s being soaked into HDG pool. But with small accessories like screws and nuts, to soak one by one would be much cost for labor cost. So it’s using Dacrome which can be soaked for a whole bags.
