INSERT CLINCHING is a mechanical fastening method used to join a
nut or or PEM® fastener to a piece of sheet metal. using special
tools to plastically form a mechanical interlock between the sheet
metals. The tools consist of a punch and a die. The punch forces
the two layers of sheet metal into the die cavity forming a
permanent connection. A permanent connection is made between the
metal and the ‘clinch nut’ or the PEM® nut. This video shows one of
