Custom Spinning Flange Nylon Insert Lock Nuts

 

These custom spinning flange nylon insert lock nuts were manufactured to our aerospace/defense customer's dimensional requirements and Class 10 specifications with black zinc nickel finish.  The combination of free spinning flange washer and nylon insert was the trickiest part of these M12 X 1.75 custom lock nuts - typically you either have one feature or the other.  Full certs were provided with the parts.
