Abstract: A locknut assembly for securing a component to a shaft is provided that includes, in one form, a locknut defining an internal cavity and an aperture having internal threads, the internal cavity defining an internal wall comprising at least one location feature. A lockwasher defines an internal cavity, an external wall comprising at least one mating location feature, and an anti-rotation feature disposed within the internal cavity and adapted for engagement with a corresponding anti-rotation feature located at an end portion of the shaft. The internal threads of the locknut aperture engage continuous external threads of the shaft, the mating location feature of the lockwasher engages the location feature of the locknut, and the anti-rotation feature of the lockwasher engages the corresponding anti-rotation feature of the shaft to limit rotation of the locknut.

Abstract: A threaded insert for use in a composite and/or honey-comb matrix has a nut member disposed within a plastic housing. The threads of the nut member have a free running thread section and a thread lock section. When a fastener is made up into the nut member, a surface on the nut member engages an opposite-facing surface on the plastic housing, thereby reversing the nut loading from tensile loading to compression loading. A thermoplastic embodiment of the nut member may be fabricated to meet the specifications of aircraft manufacturers required for the SL2334 insert, including thread reusability, tensile loading (pullout load), shear, and interchangeability with the metal component currently in use.
