Locking Washers Place the lock washer between the nut and the work surface if using a nut-and-bolt configuration, or between the fastener head and the work surface if using a tapped hole configuration. In other words, the bolt goes straight into the hole and doesn’t poke out the other end, so no nut is used.
Do you need a lock washer when using a lock nut?

When should you use a locking nut?
Locking nuts should be used when the screw joint consists of one or more soft materials. It is difficult to achieve and to maintain a high level of clamp load because the soft material deforms due to high surface pressure. This plastic deformation continues after the torque value has been applied to the screw.

The second (thick) nut is then placed on the bolt and the thin nut held to prevent rotation by a spanner whilst the thick nut is tightened to the full torque value.
How do locking washers work?
Locking washers work by exerting downward tension.Locking washers share this characteristic trait by exerting tension as well. When you twist a nut onto a bolt, it will press against the locking washer. The locking washer will then generate tension that secures the bolt in place.
