Abstract
The nut (1) is used to prevent loosening of assemblies screwed or similarly held together and has an annular groove, perpendicular to the axis and with a semicircular bottom face. An annular spring (2) in this groove is made of wire wound spirally, and it projects into the nut bore and grips the bolt. As the bolt is turned the spring turns lie over at an angle offering least resistance to bolt passage. If the bolt tends to turn in the opposite direction, the spring turns attempt to re-orientate themselves and prevent relative motion between nut and bolt.
