Nut cantilever beams are calculated to permit hundreds of installations and removals Nut cantilever beams pressing on tapered ramp of fitting groove, provides friction torque to increase resistance to vibratory conditions. Bulb at end of nut cantilever beam, when seated in fitting groove, prevents separation of nut from fitting. Accessible for reinstallation or maintenance, which is not always the case with lock-wire. Minimum weight penalty. (see weight comparison charts)
Material weight and cost are optimized based on temperature environment. Cost effective - less installation time. Removes F.O.D. potential of lock-wire. Installation is visually verifiable. A wrench is required to install nut over ramp.
