How Do They Do It? Season 12 Episode 5 Screws and More

The show, How Do They Do It?, takes viewers on an exciting journey to explore the inner workings behind some of the world's most fascinating machines and technologies. This season, in episode 5 titled "Screws and More," viewers get an in-depth look at the complex methods and processes involved in manufacturing the tiny but essential components that hold together everything from skyscrapers to tiny electronic devices.

Throughout the episode, various experts guide viewers through the intricate world of screw-making. They demonstrate the raw materials and machines required to create different types of screws, from simple wood screws to complex high-strength screws used in the aerospace industry. For instance, viewers get a glimpse at the production of self-drilling screws that are commonly used in the construction industry to fasten metal sheets together. They will learn how the steel wire is transformed into a screw by going through different stages such as forming, hardening, and thread rolling.

The episode also delves into the important role screws play in the food industry. The screws in this context are not the type used to fasten objects together, but the ones that transport food and raw materials through the production line. Viewers get a behind-the-scenes look at the complex machinery involved in the mass production of everything from chocolate and bread to pet food and pasta.

As the episode progresses, viewers also learn about the different kinds of bolts used in various industries. They discover that bolts are often customized to their precise application, whether it's in oil rigs, tractors, or bridges. Experts explain how they produce the large bolts required to hold buildings and bridges together, including how specialized coatings, such as galvanization, are applied to prevent rust and corrosion.

The show also covers nuts and washers- the food necessary for the screws and bolts. Viewers will be taken through the process that turns simple coils of raw metal into intricate shapes and sizes, from tiny washers to nuts that can support huge weights. They will learn how these components are used to complement bolts and screws and the essential role they play in ensuring firmness and safety.

Finally, the episode concludes by highlighting various innovations aimed at making screws, nuts, bolts, and washers even more effective and efficient. From using cutting-edge alloys to developing new coatings that can withstand tough environments, viewers will learn about some of the latest technologies being used to create these critical components.

In summary, How Do They Do It? season 12 episode 5, "Screws and More," offers viewers a fascinating look into the complex and intricate world of screw-making and the essential role these components play across a range of industries. From understanding how these tiny components are made to the latest innovations in screw-making technology, this episode provides a comprehensive overview of the world of screws, bolts, nuts, and washers.
