Screws are externally threaded fasteners. They can be inserted into a pre-made holes or can also be inserted through the material. Screws are used to hold different objects together as they push or pull on them. The screw’s ridges allow a screwdriver or other tool to drive the screw into the material in a circular motion.

A bolt is a type of threaded hardware fastener that is typically used to assemble two or more unthreaded components. They are designed to be placed through already drilled holes and require a nut to tighten it from the other end. They come in many configurations for various applications. A bolt is similar to a screw in appearance but does not have the sharp tip that screws generally have. In typical applications, the bolt is pushed through the drilled hole of the material and a nut is placed at the end to screw the bolt through.
