Selectively hardened fasteners with corrosion-preventative coating protect the integrity of the structure and avoid the dangers of hydrogen assisted stress corrosion cracking (HASCC), also known as delayed hydrogen embrittlement. In exterior applications or aggressive interior environments, bi-metallic or super alloy fasteners are recommended.
Labor-reduction associated with the new super alloy fasteners is expected to result in even more significant overall savings, especially on high-rise structures.
