Flexco Bolt Hinged Fastener System - Fasteners - 550 Series - Steel Joint

Sturdy hinged construction makes Flexco® Bolt Hinged fasteners ideal. A choice of sizes accommodate belts from 1/4" (6 mm) to 5/8" (16 mm) thick.

For belt conveyor applications subject to frequent length adjustments, the Bolt Hinged fastener is easy to install - and re-install. The joint can be separated simply by removing the hinge pin.

On-site installation requires hand or power tools. Our exclusive piloted bolt also simplifies installation and holds fastener plates firmly in place. For added strength and pull-out resistance, specially formed teeth penetrate deep into the belt carcass without damaging carcass fibers.
