Key Advantages
Aerotight is an all metal stiff nut - No vulnerable inserts to be affected by heat or oil.
Aerotight can be re-used many times - Self locking function will still remain effective having been used a number of times.
Aerotight will stay in position whether tightened down or not, provided the locking element is engaged - Does not have to achieve recommended torque to be effective.
