There is at least one mounting attachment (32) to receive a threaded member. The at least one mounting attachment includes a base component (60) and a spool component (80). The base component extends through an opening in the fan case body from the radially outer surface and toward the radially inner surface of the fan case body. The base component including a base portion (62), a boss (64) having a non-cylindrical profile, and a cylindrical portion (66) The mounting attachment also includes a spool component disposed on the radially outer surface and attached to the base component.
