A Tek screw, also known as a self-tapping screw, is a specialized type of screw designed with a sharp point and thread that cuts into the material it's screwed into, eliminating the need for pre-drilling. The 4-inch variant is particularly popular due to its versatile length and load-bearing capacity. It strikes a balance between being long enough to provide substantial hold in thicker materials while remaining compact enough for use in various projects.

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.
