You need a washer that'll fit over that collar so that when you put the nut on the shock, it'll seat the tophat on the washer (seated on the shock's collar/damper rod) and tighten down against the tophat. Without the washer, the damper collar is too tall and the nut taps out of thread before it clamps on the tophat.
