Moderators permissions

How can i remove the permission to make threads sticky from moderator?

There is no way to remove just that single permission. It is in the permission Can Manage Threads:

Can Manage Threads
This permission covers the rest of the thread permissions (stick, merge, split, etc).

Sticking a thread makes it so it always appears at the top of the thread listing. Merging allows a moderator to combine the posts of two threads into one thread. Splitting allows a moderator to split the posts from one thread into two threads.
