Rivet Nuts are a type of fastener used to create a strong, threaded hole in thin or hollow materials,They are commonly used in applications where you need to attach components securely but cannot access both sides of the material to install a traditional bolt or nut:

• Rivet nuts are hollow cylinders with internal threads on the inside, which allow a bolt or screw to be inserted into the threaded hole.
• Rivet nuts flanges at the top (usually at one end) that help to prevent the nut from pulling through the material during installation.
• The body of the rivet nuts deforms during installation, creating a permanent hold in the material.
