Lantern nuts, also referred to as acorn nuts with a hollow or open-top design resembling a lantern, are specialized fastening components that combine protection and aesthetics. Their unique structure features a domed cap with an open or partially open top, shielding the threaded end of a bolt from debris and environmental elements while allowing for easy inspection or adjustment of the connection. Widely used in automotive trim, furniture assembly, and decorative applications, lantern nuts offer both functional security and a polished appearance, making them ideal for scenarios where exposed threads need concealment without sacrificing accessibility.
