  • Stainless Steel Prevailing Torque Self Locking Nuts
    A2 Grade Stainless (T304) and A4 Grade Stainless (T316) are available.
    Prevailing torque nuts are a versatile locking nut without inserts. They can be used in similar applications to the more widely known designs from Aerotight, Nylock, Staytight and Philidas.
    The way they work is to slightly deform the thread on application. This makes them a single use item. If you need to be able to remove the nut, you should look at aerotight instead.
  • Aerotight Self-locking Nuts A2 Stainless Steel (T304)
    Aerotight self locking nuts are:
    All metal Stiff nut with no inserts
    Can be re-used
    Will stay in position whether tightened down or not
    No special tools required
    When assembled on the screw, 2 full threads should protrude through the nut
  • Nylon Insert Lock Nut A4 Grade Stainless Steel (T316)

    Full Stainless Steel nut with an undersized nylon insert that when fastened get deformed but not cut by the mating thread that creates a lock that will also dampen the vibrations between the thread and the nut, this also provides a moisture and gas seal. As the nylon insert gets deformed not cut by the mating thread it can be re-used a limited number of times.

    Unlike the all-metal locking nuts the nylon locking nut can be affected by high temperatures so please consider one of our other all metal locking nuts if this could be the case.
