Abstract
A fastener assembly includes a threaded member and a first lock member coupled to the threaded member. The first lock member includes a plurality of ratchet teeth. The fastener assembly further includes a second lock member including at least one lock tooth configured to engage the plurality of ratchet teeth of the first lock member. The fastener assembly has a locked configuration in which the at least one lock tooth engages the plurality of ratchet teeth and an unlocked configuration in which the at least one lock tooth is spaced from the plurality of ratchet teeth. The fastener assembly also includes at least one lock arm coupled to the second lock member. The at least one lock arm extends at least in part radially outward of the second lock member. The at least one lock arm is configured to engage a surface to inhibit rotation of the second lock member.
