Although self tapping screws and drill tail screws are both threaded fasteners, they have differences in appearance, purpose, and usage. Firstly, in terms of appearance, the lower end of the drill tail screw comes with a drill tail, similar to a small drill bit, professionally known as a milling tail, while the threaded lower end of the self tapping screw does not have a drill tail, only a smooth thread. Secondly, there are differences in their applications, as self tapping screws are typically used on non-metallic or iron plate materials with lower hardness. Because self tapping screws can drill, squeeze, and tap corresponding threads on the fixed material through their own threads, making them tightly fit with each other. Drill tail screws are mainly used in lightweight steel structures, capable of penetrating thin steel plates, and have a wider range of applications in various building and industrial structures. Finally, the usage is also different. The tip of the self tapping screw is sharp, and there is no drilled tail at the end. Therefore, before fixing, it is necessary to use an electric drill or a handgun drill to make pre drilled holes on the object, and then screw in the self tapping screws. And the drill tail screw can be used anytime, anywhere because its tail comes with a drill tail, which can be directly screwed into hard materials such as steel plates and wood without the need for pre drilled holes. Its drill tail can drill holes synchronously during the screwing process. Overall, there are some significant differences between drill tail screws and self tapping screws in many aspects, and businesses or consumers need to choose based on specific scenarios and actual needs.
In practical use, selecting the correct type of drill tail screw or self tapping screw is particularly important for the stability and efficiency of fixing operations. Enterprises or consumers can choose different types of screws according to their actual needs and scenarios to achieve the best fixing effect.
