  • Triple redundant shear bolt
    Patent number: 4725174
    Abstract: A bolt is provided with a radial, spring-loaded pawl, and an associated nut is provided with cooperating detents on its inner diameter that cooperate with the pawl so that the nut does not back off the bolt. The nut is also castellated for insertion of a cotter pin through the bolt so that the nut is further restrained from backing off. In the event that the nut backs off, the pawl prevents the bolt from pulling out of a close tolerance hole, such as a rod end fitting.
