Shank Nuts

Shank nuts are high temperature, high tensile strength nuts that are used primarily in aircraft engine applications. 

Shank nuts are  self-locking, self-retaining, self-wrenching nuts installed by flaring the nut shank with a conical tool. PCC manufactures standard shank nuts in a variety of configurations and materials to OEM standards and specifications. High fatigue thread forms are available on all designs.
