Fastener Finishes

Finishing Protects Fasteners

What are fastener finishes? Coating, Plating and Finishes can add an extra layer of corrosion protection to your fastener assemblies, in addition to making them match your final application and finish. Each finish has it's own unique benefits and drawbacks, which should all be considered before using any fastener in your project.  Mutiple finishes and treatments may be needed depending on your application to extend the life of a fastener or its finish. Below is everything you will need to know about all the different available options that we offer at AlbanyCountyFasteners.com, including painting, plating, coatings, and more.
