The acorn nut is a type of fastener which gets its name from its shape. Acorn nut is its common name and it is also called a crown hex nut, blind nut, cap nut or domed cap nut. It is a nut that has a domed top to cover the threads. This is to prevent contact with the external thread to protect the threads or protect other things the threads would rub against. In addition the dome gives a more finished appearance. They look more decorative in nature and hence used in furniture fittings and household appliances. Also known as Blind Nuts and cap Nuts, these nuts are industrially used as blinds/blanks to stop or block the ends of a line.
