All Metal Locking Nuts

All metal prevailing torque nuts are a type locking nut designed to lock and resist vibration or shock. The end thread on the nut is slightly deformed which causes it to bind with the female thread it is being applied to, thereby creating a locking action by increased friction, meaning they will not spin freely and torque via a spanner is needed to fit and remove. Ideal for applications that require protection against vibratory and other equally dynamic forces. Being all metal they do not suffer adversely from high temperatures or chemical contact like other materials such as the nylon insert in nyloc nuts.
