A bolt is like a magic stick that holds things together. Imagine you have two pieces of paper, and you want them to stay together. You could use a glue stick, right? Well, a bolt is like a very strong glue stick, but instead of using sticky stuff, it uses a special twisty stick and a nut to keep things in place. It goes through holes in the things you want to hold together, and then you twist the nut on the other side to make sure they stay tight and don’t fall apart.
Think of a bolt like a superhero helping a bridge stand tall. The bridge is made of many parts, just like a puzzle. Each piece needs to stay connected to be strong and safe for cars to drive over. Bolts are like the superhero’s power, making sure each puzzle piece stays in the right spot, so the bridge doesn’t wobble or break.
A bolt can also be like a zipper on your jacket. When you zip up your jacket, the zipper holds the two sides together to keep you warm. Bolts do the same thing but for big, heavy things like buildings or cars, making sure all the parts stay snug and secure.
