Abstract
A fastener assembly includes a threaded member including a threaded body portion and a head portion. The fastener assembly also includes a first lock member including a plurality of axially-extending ratchet teeth and defining an aperture extending therethrough. The aperture is sized to receive the threaded body portion. The fastener assembly further includes a second lock member including a base portion configured to couple to the threaded member for rotation therewith and at least one spring finger extending axially from the base portion. The at least one spring finger has a proximal end joined to the base portion and a free end opposite the proximal end. The second lock member has a lock position in which the free end of the at least one spring finger is configured to engage the plurality of axially-extending ratchet teeth and an unlock position in which the free end of the at least one spring finger is spaced from the plurality of axially-extending ratchet teeth.
