A vibration-reducing apparatus for an assembly comprising a first member including a latch and a second member including a striker may include a threaded post having arm members extending outwardly therefrom, the threaded post being rotatably advanceable in discrete increments in a threaded opening extending through the first member such that, in a closed position of the first and second members, a distal portion of the threaded post extending through the first member contacts the second member upon rotational advancement of the threaded post in the threaded opening; and a locking region arranged to interact with at least a portion of the arm members, the rotational advancement of the threaded post in the threaded opening and contact with the second member reducing an engagement distance between the latch and the striker with the first and second members in the closed position, and attenuating vibrations between the latch and the striker.
