Category Details

A selection of Aerotight Nuts. Aerotight is a Registered Trademark and can only be applied to goods manufactured by the Premier Screw and Repetition Company Limited.

  • All-metal, self-locking nut designed to stay in place even under severe vibration. Works by using a locking collar that is deflected to grip the bolt's threads, creating a "prevailing torque" that prevents loosening.
  • All-metal construction allows them to be used at higher temperatures and makes them resistant to oil.
  • Also known as an Aerotight lock nut or Stiff Nut.
  • Any company infringing the registered trade mark may be liable to legal proceedings.
  • Aerotight nuts should not be used on damaged or interrupted threads.
  • When assembled on the screw at least two threads should protrude through the Aerotight nut.
  • Advantages: Will not work loose. No other locking device needed.
