Abstract
A gas turbine engine mid-turbine frame includes an annular case that has a hole. A tie rod with a first end extends through the hole. The first end includes a threaded portion. A nut is secured to the threaded portion to clamp the tie rod to the annular case. A tab washer is arranged between the nut and the annular case. The tab washer interlocks the nut to the case to prevent relative rotation therebetween.
