We all have aftermarket items installed on our SS. I just found loose screws on my Polaris cell phone holder....I reinstalled the screws with blue lock tight on the threads...every item we install with screws or bolts should have some type of thread lock on the threads.... Everything vibrates going down the road....my loose screw was literally being held by the very last thread and I found it right after a ride.
Buy a bottle of thread lock and remember to use it on every screw and bolt.
