Aerotight Nut

aerotight nutA torque prevailing nut for all metal construction. The nut is slotted in two places which, after the nut has been tapped, are bent slightly inwards and downwards. When the nut is screwed onto the bolt thread the two slotted parts are forced back to their original position.  Their stiffness causes the nut threads to bind onto the bolt threads and thus provides a prevailing torque.
