FASTENERS COATINGS 

Screws, bolts and fasteners serve a function, but how well they do their job usually depends on the coating. It’s the coating that allows all fastener types to perform in harsh conditions by providing higher strength, preventing corrosion and resisting extreme temperatures or chemicals.

fastener’s application determines which coating you need, of course. Coatings should also maintain uniform thickness and critical tolerances for parts with complicated geometries. If you’re part of a global supply chain, consistency in worldwide environmental compliance will be especially critical.
