Polymer Marine Lock Nut

Q: I’m looking for a polymer insert locknut for a marine environment.  Can you make any suggestions?

A:  In your marine lock nut application, the polymer you should consider for the locking mechanism would be PVDF (Kynar). PVDF polymer in combination with the lock nut would perform very well in a marine environment. This polymer will not be affected by sea water or UV and is much more stable than Nylon.
