What is the definition of long life? The answer would vary greatly depending upon the subject. For instance, the life expectancy of an African elephant on the Serengeti would be substantially different than that of a mosquito on your forearm.

Unfortunately for the metal roofer, the same nebulous and misleading signals are sent when some of Dynamic Fastener’s competitors claim their fasteners have a long life coating. Once again, “long life” is just a relative phrase.

To eliminate unnecessary concerns on behalf of its valued customers, Dynamic Fastener quantifies the meaning of “long life.” Since Dyna-Coat premium coating passes the 1,000-hour salt spray test, the company proudly proclaims “1,000 Hour” right next to the word Dyna-Coat. Rarely, if ever, does Dynamic Fastener see its competitors touting the tests that their screws pass. That is a suspicious omission.

To paraphrase the famous commercial, “What’s on your fastener?” Removing the uncertainty on this very important topic is easy. Specify Dyna-Coat 1,000-hour salt spray premium coating on all screw requirements. 

Dyna-Coat is a premium organic polymer coating designed to provide corrosion resistance for metal fasteners. Fasteners coated with Dyna-Coat exhibit excellent resistance to marring, chipping, and abrasion. The color of the coated fastener is metallic silver. Dyna-Coat employs several forms of corrosion resistance, such as replacement, inhibition, envelopment, and electrochemistry. These coated fasteners also have a strong resistance against acid and alkaline chemicals.
