Loosening-resistant threaded fastener system and method of use |
摘要 |
A loosening-resistant threaded fastener system and method of use includes a washer that is axially movable on a threaded stud, a threaded nut having threads which cooperate with the threaded stud, and a washer anti-rotation mechanism to prevent the washer from rotating on the stud about a fastening axis. One of the washer and the nut may include a plurality of protrusions while the other of the washer and the nut has a plurality of detents. The protrusions and the detents engage one another at a plurality of angular positions. Rotating the nut on the stud while in contact with the washer results in distinct, audible clicks which may be counted to obtain a pre-determined tightness.
