How Flexco® Fasteners Work Flexco® Bolt Hinged fl exible joint for belts operating over small pulleys. Because the joint is easily separated by simply removing the hinge pin, entire belt sections may be added or eliminated. Bolt Hinged fasteners provide a Bolt Hinged model is fastened to the belt ends with high strength bolts. The Designed as a compression fastener, the Flexco® Applications • Construction Equipment • Road Machinery • Coal, Salt, Potash Mines • Stacking and Stockpiling Belts • Other Applications Involving Smaller Pulleys How to Specify the Correct Flexco® Bolt Hinged Fastener 1. Determine Belt Tension (PIW). 2. Measure your Belt Thickness. 3. Measure the Diameter of the Smallest Pulley in your Drive with Belt Wrap more than 90°. 4. Choose the fastener size that is appropriate for your specifi cations in the selection chart below. Fastener Metal Selection Steel. For most applications, plated steel is recommended. Stainless Steel. Type 316 Stainless Steel provides extra resistance to abrasion, magnetic attraction, and corrosion from acids and chemicals. MegAlloy® Everdur® to wear and abrasion. . For superior resistance . Spark-free material compared to steel and fully non-magnetic. Installation Method Fasteners can be installed in the shop or on-site with either simple hand tools or power tools. bolts compress the plates into the belt cover. Additional holding capability is provided by the fastener teeth that imbed in the belt without damage to the belt carcass. This combination distributes the splice tension across the entire plate width while the teeth secure the fastener into the belt carcass to resist pull-out.
