More information on fastener coatings/materials
These coated fasteners possess a level of corrosion resistance that makes them suitable for use in some exterior and corrosive environments
and with some preservative-treated woods. For applications in higher-exposure applications, consider type-300 series stainless-steel fasteners
for superior corrosion resistance. See additional important information before selecting a fastener for a specific application.
