Locking mechanisms with deflectable lock member

A method of assembling a locking mechanism for a fastener including a threaded body portion, said method comprising:

• providing a first lock member including a plurality of radially extending ratchet teeth, the first lock member defining a first aperture extending therethrough, the first aperture sized to receive the threaded body portion;
• forming a base portion of a second lock member, the base portion defining a second aperture extending therethrough, the second aperture sized to receive the threaded body portion;
• forming at least one tab of the second lock member, the at least one tab having a proximal end joined to the base portion and a free end opposite the proximal end, wherein a plurality of radially extending teeth are formed on an inner side of the free end of the at least one tab;
• bending the at least one tab at an angle relative to the base portion such that the at least one tab extends axially from the base portion, wherein the second lock member is positionable between a locked configuration in which the plurality of radially extending teeth are configured to engage the plurality of radially extending ratchet teeth and an unlocked configuration in which the plurality of radially extending teeth are spaced from the plurality of radially extending ratchet teeth, wherein the base portion and the at least one tab are a single piece;
• and
• forming at least one anti-rotation feature of the second lock member, wherein the at least one anti-rotation feature is configured to engage an anti-rotation structure and prevent rotation of the second lock member when the first lock member is rotated.

A locking mechanism for a threaded member, the threaded member including a threaded body portion, said locking mechanism comprising:

• a first lock member including a plurality of radially extending ratchet teeth;
• and
• a second lock member comprising:
• a base portion defining an aperture extending therethrough, the aperture sized to receive the threaded body portion;
• and
• at least one tab extending axially from said base portion, said at least one tab having a proximal end joined to said base portion and a free end opposite said proximal end, wherein said second lock member further comprises a plurality of radially extending teeth on an inner side of said free end of said at least one tab, wherein said second lock member is positionable between a locked configuration in which said plurality of radially extending teeth are configured to engage said plurality of radially extending ratchet teeth and an unlocked configuration in which said plurality of radially extending teeth are spaced from said plurality of radially extending ratchet teeth, wherein said base portion and said at least one tab are a single piece.
