A thread protector for use with a threaded end of a tubular member comprises a first end having an opening with an inside diameter, a second end, and an interior having an inside diameter that is substantially the same as the inside diameter of the opening. The interior is adapted to accept and surround the threaded end. The thread protector may be actuated between a locked and an unlocked configuration. When the thread protector is in the locked configuration, a portion of the inside diameter is reduced, as compared to when the thread protector is in the unlocked configuration, so as to securely mount the thread protector to the threaded end.
