Drop Forged Chains with Bolt-on Flights
4B102BNA, 4B125BNA, 4B142BNA, 4B142BHA, 4B160BNA

The Bolt ‘N’ Go flight system is a revolutionary assembly method for drop forged chains. Link and flight assembly is made easy by using a standard bolt and mechanical lock nut with a high strength, heat treated hollow pin. There are no circlips and no intricate assembly is required. There is no welding of flights, no need to remove chain from the conveyor for installation, and no issues with strength. Just bolt the links and the flights together. It’s easy, simple and reliable!
