ESNA Aerospace

ESNA Aerospace is a manufacturer of self-locking fasteners, bushings and precision machined parts for commercial aerospace and military markets. The company traces its history to 1927, when the elastic stop nut was introduced in the United States, and calls itself the pioneer of self-locking fasteners.
