These nuts have good chemical resistance and may be mildly magnetic. They have threads that float within the body so you can install a bolt at a slight angle to align off-center parts. Knurls on the bottom of the nut hold them firmly in place. Press them into a drilled or punched hole with an installation tool or an arbor press. Installation requires access to both sides of the panel.
