Zusammenfassung:	A spanner nut (92) for a bearing compartment of an engine with a bearing stack (90) on a first shaft (48) that rotates about an engine centerline (12) includes a body (100), a piloting hook (104) connected to the body (100), a second threaded portion (112), and a channel formed by the piloting hook (104). The piloting hook (104) includes first and second extensions (106,108). The first extension (106) is connected to and extends radially inward from the body (100). The second extension (108) is connected to and extends in an axial direction from the first extension (106). The second extension (108) includes a radially outward facing surface (110). The second threaded portion (112) is configured to engage with a first threaded portion (98) on an end (96) of the first shaft (48). The channel is configured to receive the end (96) of the first shaft (48). The piloting hook (104) is configured to draw the second extension (108) radially outward as the spanner nut (92) is compressed.
