Flexco^® Bolt Hinged Fastening System

The Flexco^® Bolt Hinged Fastening System is ideal for belt conveyor applications subject to length adjustments because the joint can be separated easily by removing the hinge pin. A combination of penetration and compression delivers strength and reliability to belts operating over smaller pulleys.

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.

Fastener Material	Magnetic	Abrasion Resistant	Chemical Resistant	Rust Resistant	Sparking
Galvanized Steel	Yes	Good	Poor	Fair	Yes
Stainless Steel (300 Series)	Slightly	Good	Good to Excellent	Excellent	Yes
MegAlloy^®	Yes	Excellent	Poor	Poor	Yes
Everdur	No	Poor	Poor	Poor	No
