corrosion's always been a problem with the nuts we been running out in the field, does this one have any kind of protective coating on it?
Answer by: Customer Support on Sep 18, 2025, 9:47 PM
Carbon steel with a zinc clear trivalent chromate finish is what you're getting here. Eaton calls it Dura-Kote plating, and it's built specifically to hold up better against rust and corrosion than a standard bare steel part would. For field use where moisture and grime are a constant issue, that finish makes a real difference over time.
