I didn't have a socket wrench when I installed it which makes the job pretty difficult and slow if all you have is a combination wrench. So, that's the down side because the hitch bolt is threaded. The upside of that problem is that the threads really stabilize the hitch to the vehicle. There is virtually no wiggle at all once that bolt is tightened down. So, yes, you can buy a locking hitch bolt for less money but you won't find one that will secure your bike rack so tightly to your vehicle.
