Difference between a bolt and a screw

Difference between a bolt and a screw

Bolts and screws are both works similar and known as fasteners that help hold objects in place and hold them together. Some people think that bolt and screw are the same but the reality is not the same, all screws are not bolts. There aren't really hard differences between a bolt and a screw, but they do have some specifications. Screws and bolts are highly used in the manufacturing industry.  

Bolts and screws are the basics of any machinery, but we rarely pay attention to them. Suppose we buy a car but never think about the car machinery and wheels attached to the car body. Groups of screws and bolts are used to attach them. A screw has a specially shaped head. 

Here we know about the difference between a bolt and a screw.

With a few exceptions, the end of the bolt is larger than the shaft. The carriage bolt and J-bolt are among those exceptions. There is one difference between a bolt and a screw is that the bolt requires a nut to secure it and a screw doesn't require it. 

Both screw and bolt belong to the same family. They were some of the earliest fasteners in use. Fasteners suitable for different industrial applications, here are the types of screws and bolts.

However, the most appropriate way to differentiate screw and bolt is to understand that, in short, the main difference between screw and bolt stems from the way they are used.

Both screw and bolt are externally threaded fasteners. Screws, on the other hand, can be placed within pre-tapped holes and penetrate the material.
