What are screws?

Screws are one of the most common elements found in machines and are used to fix things together. A screwdriver is usually required to tighten or loosen screws.

Screws use a helix to increase strength and speed. Moreover, screws have a sharp pointed tip which helps in cutting through different materials. Additionally, screws with a larger head provide more resistance than those with a small head. So, the larger the head, the harder it is to unscrew it.

Screws have been around since 1839 when Jean-Baptiste Auguste Schweitzer first invented them. They were originally designed for locksmithing projects but soon evolved into more complex applications like construction or manufacturing.
