S-RTM4-1ZI
All Metal, RT® Free-Running Locknuts
PEM® 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.
