[Technical Information] On the Principle of Loosening: Advanced Edition

It provides a detailed explanation of "rotational looseness" and "non-rotational looseness" using diagrams!

The loosening of screws can be broadly classified into two types. There is "rotational loosening," which occurs when the male and female threads rotate relative to each other in the direction of loosening, and "non-rotational loosening," which occurs even when they are not rotating relative to each other. Furthermore, screws are used extensively in our daily lives. However, when screws loosen when we do not want them to, it can not only disrupt our lives but also lead to major accidents. It is important that screws do not loosen when we do not want them to, and that they do loosen when we want them to. Research on screw loosening and prevention is considered urgent. 【Classification of Loosening】 ■ Rotational Loosening ■ Non-Rotational Loosening *For more details, please refer to the PDF document or feel free to contact us.
