Nuts

A spring nut, also known as a cage nut or snap nut, is a type of fastener used to secure objects within a panel or enclosure, particularly in electronic and rack-mount equipment applications. Spring nuts are designed to be used with square or rectangular holes in metal panels, such as those found in server racks, cabinets, and chassis. They are commonly used in data centers, telecommunications, and other industries where equipment needs to be securely mounted.
