ESNA

Founded in 1927, ESNA is a defense component supplier based in North Richland Hills, United States working in air systems.

ESNA, part of Novaria Group, is a manufacturer of self-locking fasteners, lock nuts, nut plates, precision bushings and precision-machined parts for commercial aerospace and military markets. Founded in 1927, the company traces its origins to the elastic stop nut, a self-locking fastener first brought to the United States under license. ESNA operates facilities in North Richland Hills and Pocahontas, US, and a sales office in Lachine, Quebec, Canada. Operations include in-house metal finishing (cadmium, zinc nickel and passivation) with X-ray inspection, and precision machining from aerospace materials such as titanium and nickel alloys. The company states that it performs about 85% of its production in house. ESNA has supplied fasteners for military aircraft since 1943, when the U.S. Air Force approved its fasteners for use on fuselages and engines, and it maintains a dedicated military and defense product offering. The company states it is AS9100-certified and works to ISO 9001 quality requirements.
