Abstract
A fastener includes a threaded pin and an internally threaded collar. The threads can freely be run without impediment during tightening. After the fastener is tightened, a tool engages a shoulder on the collar and presses a deflector against the collar on the pin to deflect it so as to form a lock against loosening.
