Abstract
A system for preventing rotation of fasteners is provided that includes secondary locking devices. The system may include multiple fasteners that extend parallel to each other and may be arranged in a generally circular pattern. Multiple secondary locks may be arranged concentrically outside of the fasteners and have radially extending teeth so that teeth of adjacent secondary locks engage each other for preventing rotation of the fasteners. The secondary fasteners may have central openings that are larger than the fasteners to allow for substantial back-and-forth rotational movement, which may be between about 5 to 20 degrees of travel, of the secondary locks upon the fasteners before being stopped by the engagements of the secondary locks and fasteners. Inner and outer peripheral surfaces of the secondary locks may have different axes of symmetry which may allow the secondary lock teeth to be arranged asymmetrically relative to the fasteners.
