Nut Type | Aerotight Nuts |
Aerotight Nuts are a type of all metal prevailing torque self-locking nut. This type of lock nut requires a torque (the prevailing torque) to rotate the nut down the thread. The prevailing torque is the locking feature. The advantages of the all-metal design is that the nut can be used at elevated temperatures (up to 300 C) and is not affected by oil. The finish on the nuts is BZP (Bright Zinc Plating). The nuts are available in metric and UNF threads. The nut can be re-used and still maintain a locking action. To achieve the full locking action of the nut it is recommended that at least two bolt threads should protrude through the top of the nut.
