Floating nut plates are low profile and lightweight plates used to install a captive nut behind a panel. The floating nut allows for an assembly that is not perfectly aligned. These lightweight, low-profile nut plates are designed for blind mounted applications where it is impractical to use hex nuts or where it is desirable to have an attached nut for ease of maintenance. F5000/MS21059 Series floating two-lug nut plates are made of carbon steel or alloy steel and are cadmium plated. They are superseded by NASM21059 series.
