These are the most common and inexpensive self-locking aircraft nuts. Almost infinitely reusable, tensile strength rated at 125,000 psi with 250°F temperature rating. Thin pattern (AN 364) nuts should only be used in shear load applications.

These free-spinning low profile nuts are used to lock rod ends and other threaded components into position. Available in right and left handed threads. Gold cad plated steel.

These nuts feature a good combination of light weight and high strength (160,000 psi tensile). Available in steel (450°F) and stainless (900°F).
