IVD Coated Fasteners

I have been given some information concerning IVD coatings used for corrosion protection from salt air environments on fasteners. I haven't found fasteners yet that are indicated to have such a coating unless there is a different common name. Have you any information concerning IVD coatings and where such fasteners are available?

Hi, Kenneth. I don't think Ivadized nor aluminum plated fasteners will be found except in aircraft manufacture. It is my understanding that the basic reason you would Ivadize a fastener is for compatibility with aluminum parts you are joining while avoiding cadmium plating (the traditional but bioaccumulatively poisonous finish for such purpose). A jobshop can Ivadize for you, but I don't think you'll find Ivadized fasteners on a shelf.

IVD (Ivadize / Ion Vapor Deposition) is a process developed by the Military as an alternative to cadmium plating (corrosion preventative), which is a hazardous coating process. It probably comes at a premium price, so most likely you won't find fasteners utilizing it readily available at a price you're willing to pay.
