Description
A spring nut, also known as a captive nut or cage nut, is a type of fastener often used in sheet metal or panel applications. It is a threaded nut with one or several springs attached to its backside. The purpose of the springs is to provide a secure and self-retaining grip onto the panel or sheet metal when inserted into a pre-punched or pre-drilled hole. This allows for quick and easy installation without requiring access to the backside of the panel. Spring nuts are commonly used in industries such as automotive, electronics, and HVAC for mounting components, securing wires or cables, and other applications where accessibility and speed of installation are crucial.
