Cap nuts, also known as crown hex nuts, blind nuts, or dome nuts (UK), have a curved end on one side. When used with threaded fasteners with external threads, the domed tip surrounds the external threads to protect the threads or prevent nearby objects from coming into contact with the threads. Also, the dome provides a more polished look.
Cap nuts are usually made of brass, steel, stainless steel (low carbon content) or nylon. They can also be chrome-plated and mirror-finished.
There are two types of cap nuts. One is a low, or standard cap nut. The other is a tall cap nut. Tall cap nuts are wider and taller to protect extra long studs. There are also self-locking cap nuts with twisted threads in the hex area to create a tight friction fit to prevent the nut from loosening due to vibration.
