Abstract
A fastener assembly is provided and includes a fastener member and a washer member. The fastener member includes an end, an opposing head, and an elongated threaded body portion extending therebetween. The threaded body defines a center axis. The head includes a pawl arm having a pawl tooth and a flange. The washer member includes an axial aperture formed therethrough and a lock tab extending therefrom. The lock tab is configured to be received within a recess defined in a substrate member to rotationally fix the washer member relative to the substrate member. The washer member further includes a plurality of lock teeth. The pawl tooth is configured to intermesh with the lock teeth to allow rotation of the fastener member relative to the washer member in a first direction about the center axis, and substantially prevent rotation in an opposite second direction about the center axis.
