Screw Plug
A screw plug typically refers to a threaded, cylindrical device designed to be inserted into a hole or opening, primarily for the purpose of sealing, closing, or securing the opening. The threaded design allows the screw plug to be easily screwed into or out of the hole, providing a simple and effective means of closure. Screw plugs are commonly used in various applications, such as plumbing, machinery, and equipment, where they serve to prevent the leakage of liquids or gases, protect internal components, or facilitate access for maintenance and inspection.
