Plating Guidelines

Black Nitride || Cadmium Platings || Dry Film Lubricants || Electro-Tin/Solderable Platings || Nickel Platings || Passivation of Stainless Steel || Zinc Platings

In addition to providing cosmetic advantages, the function of most platings, coatings and finishes is to provide a certain level of corrosion resistance. Customers should be aware that if they order and receive un-plated or uncoated steel fasteners (usually designated with an “X” part number suffix), the parts may not have the necessary corrosion resistance and will rust, corrode, discolor or otherwise degrade at a much more accelerated rate than finished products. While we can investigate, in most cases PennEngineering cannot be responsible for quality issues that may arise from these circumstances.
