Abstract
A blocking nut ensemble for positional placement on a threaded shaft comprises a first internally threaded nut for threading on a shaft and including a first abutting face having intermediate inner and outer sidewalls depending therefrom and defining an annular groove in the first nut. A second internally threaded nut for threading on the shaft is axially aligned with the first nut. The second nut has a second abutting face and an annular locking flange extending therefrom wherein the annular locking flange is radially positioned in registration with the annular groove in the first nut. The annular flange of the first nut is received in the annular groove of the second nut when the first abutting face abuts the second abutting face thereby locking the first nut to the second nut.
