Threaded fastener with improved resistance to backing out of a blind hole

A threaded fastener composed of separate upper and lower portions with a small axial freedom of movement relative to one another. After being threaded into a blind hole together, the portions are moved relative to one another and locked in place, creating a distribution of stresses which resists bac...

Zusammenfassung:	A threaded fastener composed of separate upper and lower portions with a small axial freedom of movement relative to one another. After being threaded into a blind hole together, the portions are moved relative to one another and locked in place, creating a distribution of stresses which resists backing-out of the fastener without the various drawbacks which limit prior art solutions to this and similar threaded fastener applications.
