ABSTRACT:
An engagement fitting attaches to a rotational fastener, and is anchored to a point stationary relative to the fastener. A rotational coupling attaches the engagement fitting to an anchor member, allowing uni-directional rotation of said engagement fitting on the rotational fastener, relative to the anchor member, about the fastener axis, in a loosening direction of said rotational fastener, to prevent self-loosening of the fastener.
