Which of the following describes hull integrity fasteners?

Hull integrity fasteners are specifically designed to maintain the structural integrity of marine vessels. They are often subjected to challenging conditions, including exposure to sea pressure. The option that describes hull integrity fasteners accurately notes that these are male threaded items. The term "loaded by sea pressure" indicates that they are engineered to withstand significant external forces from water pressure, which is particularly important when considering the safety and durability of the vessel's hull.

In marine environments, ensuring that fasteners can handle such pressures is crucial to preventing leaks and structural failures, which could have severe consequences for the vessel and its occupants. Therefore, the emphasis on male threaded items highlights their typical usage where they are secured into female threads, providing a stable and secure fit that is essential in these applications.
