The use of self-tapping screws is a common and effective method in various industries for joining two or more materials. These screws are designed with a special thread that allows them to cut their own path into the material as they are being driven in, eliminating the need for pre-drilling holes. This makes them an ideal choice for situations where time and convenience are paramount, such as in mass production or in situations where access to the back side of the material is limited.

Furthermore, double-threaded studies can help to reduce the impact of confounding variables on the research findings. Confounding variables are those factors that influence the outcome of a study but are not directly related to the research question being investigated. By controlling for these variables in both studies, researchers can ensure that any observed differences between the two groups are due to the experimental manipulation rather than other extraneous factors.
