(Not on the neck; its on the Bridge)

I thought that my string lock screw was the problem, so I bought new string blocks + string locker bolt. I still have the same problem:

As I turn the string screw with the allen wrench, it just won't go in. It turns, but it won't go in. What's the problem?
is it stripped? by some chance
