The Difference Between Bolts and Screws

A bolt is an object with a hexagonal top and a spirally threaded shaft. A screw can be broadly used to refer to any object with external threads, of which bolts are a type. To use a bolt, we generally insert it through a hole in an object, then place a nut on the end of the bolt and tighten it.

 

What is the Difference Between Bolts and Screws?
The main difference between a bolt and a screw is that a bolt is an object with a hexagonal top and a spirally threaded shaft, and it must be used with a nut. Screw, on the other hand, is a common term that broadly refers to any object with external threads.

 

This shows that a bolt is actually a type of screw. To use a bolt, we generally insert it through a hole in the object to be secured, then place a nut on the end of the bolt and tighten it.

 

Screws come in many different types, each with different usage methods. For example, screws are usually screwed directly into an object, unlike bolts, which require a nut to secure them.
