History of Fasteners To survive, the fasteners industry is then directed its attention to highly engineered, value-added fasteners to reduce assembly, labor and inventory costs Aerospace industry was set as a target ! 6

Importance of Fasteners in the Aerospace Industry Today, aerospace/defense industry is responsible for about 14% of consumption. Ken Long, an industry analyst at the Freedonia Group, believed some growth is anticipated in the long-term outlook of fastener industry. 7
