PEM® S-RT™ free-running locknuts are free-running until clamp load is induced. A modified thread angle on the loaded flank provides the vibration resistant locking feature.
  • Screw turns freely until a clamp load is applied.
  • Resistant to vibrational loosening.
  • Back side of panel is flush or sub-flush for screw installation.
  • Locking feature reusability is not affected by number of on/off cycles.
  • Uses same mounting hole and installation tooling as standard S™ nut fasteners found in PEM® Bulletin CL.
