Claim 11:
12. A system for reducing vibration between a first aircraft component and a second aircraft component, the first and second components being connected using a fastener, the fastener having a head, the system comprising:
an insert configured to receive and secure the fastener head such that the insert rotates with the fastener;
a shelf extending outwardly from an edge of the insert, the shelf configured to be introduced into a gap created between a portion of the first component and a surface of the second component, the shelf also being outwardly ramped creating a plurality of thicknesses in a direction of rotation; and
the system being further configured such that a rotation of the fastener head results in engagement of a portion of the ramp having a greater thickness selectively increasing a pressure in the portion.
