This Giant Screw
Think you know all there is to know about screws? Guess again. This is one of the biggest screws anyone has ever seen. It’s used to secure solar panels. But its size isn’t the only thing that is interesting about it. These types of screws are generally made out of anodized aluminum because they are highly resistant to corrosion and light. This guarantees that they won’t degrade when exposed to the intense elements required to power a solar panel.
