ABSTRACT:
A self-locking nut mechanism is operable to be mounted on a bolt element to secure structural members together and includes a nut body having a cylindrical portion and a flange portion. A through hole in the nut body has a first hole portion with one diameter and a second hole portion with another larger diameter, the nut body having a transition section between the first and second hole portions with such transition section having a first tapered part. A split nut is disposed in the second hole portion, the split nut being split into at least two split-nut sections. The split nut has a longitudinal end having a second tapered part. A spring in the nut body biases the split-nut toward the first tapered part such that the first and second tapered parts are biasingly engaged. The bolt element has external fastenings, and the split-nut has internal fastenings. The bolt element is axially insertable into the split nut such that the external fastenings engage the internal fastenings to temporarily separate the split-nut section against the bias of the spring as the first tapered part engages the second tapered part, the bolt elements being precluded from being withdrawn axially from the split nut by the mating of the external and internal fastenings.
