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.
The type of material and size needed for a screw is determined by the application it will be used for. Some different materials include:
