Abstract: A self-locking nut designed to work with a male thread's that have a slot, keyway or hole along their threads. A novel locking ring (13) placed in a cavity (23)in one end of the nut. One or more fingers (24) on the locking ring lock into a slot, recess, hole or keyway in the male thread and multiple projections on the clip lock into recesses (22) in the female component. By locking the male component to the clip and the female component to the clip the device locks the male component to the female component.

Abstract: A self-locking threaded connecting device comprising a male component (11) with a recess locking thread type (31) and a female component (12) with a flexible thread segment (21). Tension from the alignment of the internal flexible thread segment urges projections (22) of the flexible thread segment into the recesses (32) of the recess locking thread and thereby prevent the threaded fastener from loosening and coming apart in response to axial pressure optionally combined with vibration, expansion, contraction or other movement. The projections and recesses are shaped so that the faces glide by each other and unlock with the application of adequate torque. The two threads are designed to work together. The female component when used with a standard male component without recesses provides resistance to inadvertent loosening.

Abstract: A fastener having an internally threaded nut body, an externally threaded stem and a lock collar keyed to the nut body. The lock collar has a plurality of spring arms extending radially at an angle into the internally threaded bore of the nut body. During setting of the fastener, the stem is rotated in a tightening direction relative to the nut body. However, when the fastener is fully set, the spring arms will engage axial grooves in the stem to prevent relative rotation in a loosening direction between the nut body and the stem. This configuration forms a positive mechanical lock between the stem and the nut body and prevents the fastener from loosening and losing its clamping force, even when the fastener is subjected to high levels of stress and vibration.
