FASTENER METALS AND AVAILABILITY
To maximize fastener service life, fastener material must be matched to the application. Flexco manufactures fasteners from a broad range of materials. Our selection makes it easy to specify a fastener that will deliver maximum performance in a variety of conditions—from wet and abrasive applications to highly corrosive environments.
Galvanized Steel: For basic applications, galvanized steel is recommended. It is magnetic, offers good abrasion and rust resistance, but is not recommended for corrosive environments.
Stainless Steel: Stainless steel provides extra resistance to abrasion, magnetic attraction, and corrosion from acids and other chemicals.
MegAlloy®: Features superior resistance to wear and abrasion. Provides several times the service life of steel. Not recommended where
impact of corrosion is a problem.
Everdur: A corrosion-resistant copper and silicon alloy. Fully non-magnetic and spark-free, low in resistance to abrasion.
