Laminated nut with center tension sleeve

A laminated nut, comprising:

• a conical spring, top disc and a conical spring, bottom disc stacked upon each other defining a laminated stack having a common central bore and a outer wrench engaging surface, the conical spring disc including projections;
• a two-piece tension sleeve located in said central bore, the tension sleeve having a first tension sleeve member and a second tension sleeve member having opposed edges and an outer wall shaped to substantially conform with the shape of said central bore and an inner wall which is threaded;
• the tension sleeve having a first end and a second end, the first end of the tension sleeve including an outwardly extending upper flange and the second end including an outwardly extending bottom flange, the upper flange and the bottom flange being shaped and dimensioned to retain the top disc and the bottom disc in a stacked relation with the tension sleeve fixedly secured to the laminated stack, such that the conical spring discs and tension sleeve rotate together as a unit;
• and
• wherein the edges of the first tension sleeve member and the second tension sleeve member are separated by voids into which the projections of the conical spring discs fit for integrating the laminated stack with the tension sleeve.
