Fastener Components: MacLean-ESNA Nylon Insert Lock Nuts

MacLean-ESNA Nylon Insert Lock Nuts Key Details

In the 1930s, manufacturers were looking for a threaded fastener that would positivity resist the loosening effect of vibration.   Thus, the Elastic Stop Nut Corporation of America was formed.  The history and tradition of the ESNA lock nuts lives on with MacLean-ESNA.

See the red ring...that's The Red Nylon Ring of ReliabilityTM.  It’s the color of the highest quality self-locking fastener you can buy.  It means you have a genuine MacLean-ESNA Nylon Insert Lock Nuts.  The color Red tells you that you’re buying over 80 years of aerospace and industrial fastener experience.

The Elastic Stop Nut product fastener product line is very wide, giving the design engineer the advantage of being able to select the exact features most important to his individual requirements; from 60 milligram brass nuts to 16 pound high strength heavyweights, all self-locking. We have hundreds of designs of special and self-locking fasteners, including metric, available.

Our ESNA lock nuts may be machined, but they embody the spirit of our MFCS motto Formed Through IngenuityTM.
