Threaded fastener for a fastening element, fastening rail for an aircraft cabin, and aircraft provided therewith

A threaded fastener for a fastening element, the threaded fastener comprising:

• a threaded fastener body which comprises:
• a thread for the fastening element, and
• a blocking mechanism is arranged on the threaded fastener body in an integrated manner, the blocking mechanism being configured to be switched between a blocked state and an unblocked state, the blocking mechanism being configured to block a relative rotation of the threaded fastener body relative to the fastening element by means of a blocking element in the blocked state, and to make the relative rotation of the threaded fastener body relative to the fastening element possible in the unblocked state,
• wherein the blocking mechanism comprises an actuating pin which, during a change from the unblocked state into the blocked state, is configured to grip the blocking element and press the blocking element along a radial direction of the threaded fastener body such that the fastening element is gripped in a positively locking manner, and further configured to make a radial movement of the blocking element away from the fastening element possible in the unblocked state,
• wherein during the change from the unblocked state into the blocked state, the actuating pin is configured to move with an axial movement along an axial direction of the threaded fastener body, and
• wherein during the change from the unblocked state into the blocked state, the actuating pin is further configured to move with a radial displacement along the radial direction.
