PEM® PEMFLEX® self-locking, self-clinching fasteners retain their repeated use and effective prevailing locking torque.
  • Shoulder provides increased performance.
  • Flexing action permits repeated use and effective locking torque.
  • Flange provides positive stop during installation.
The thread locking performance of Types LK, LKA, and LKS PEMHEX self-clinching fasteners (with MD finish) is equivalent to applicable NASM25027 specifications. The self-clinching feature is the same tried and proven designmore
