Bolt facts for kids
A bolt is a special kind of fastener that has grooves, called threads, on its outside. Bolts are often confused with screws because they look similar. Both are used to hold things together!
The main difference between a bolt and a screw is how they are used. A bolt usually works with a nut. The nut screws onto the bolt's threads to create a strong connection. A screw, on the other hand, usually doesn't need a nut. Its threads are designed to cut into a softer material, like wood, to hold it in place.
Sometimes, it can be tricky to tell them apart. Some people even think of screws as bolts that don't need a nut!
What is a Bolt?
A bolt is a metal rod with a head at one end and threads along part of its body. These threads are like a spiral staircase. They are designed to match the threads inside a nut. When you turn a nut onto a bolt, the threads grip each other tightly. This creates a very strong hold.
How Bolts Work
Bolts and nuts work together to join two or more objects. Imagine you have two pieces of wood you want to connect. You would drill a hole through both pieces. Then, you would push a bolt through the holes. Finally, you would screw a nut onto the other side of the bolt. As you tighten the nut, it pulls the two pieces of wood together, holding them firmly.
Where Are Bolts Used?
Bolts are super important in many places! You can find them in:
- Cars and Bikes: They hold engine parts, wheels, and frames together.
- Furniture: Many tables, chairs, and beds use bolts for strong joints.
- Buildings: Large structures like bridges and skyscrapers use huge bolts to connect metal beams.
- Machines: From washing machines to robots, bolts are essential for assembling parts.
They are used whenever a very strong and secure connection is needed.
