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.
