Aerospace industries are one of the main industries indulging in fastening solutions for all their utilities. Right from the aircraft assembly to every bit of utility in case of permanent threads, fastening solutions come in handy as they provide scope to reverse an assembly as the fasteners pave way for non permanent joints. The construction is a combination of both light weight and heavy weight and a combination of metal fasteners are used in the aerospace industries. To avoid bimetallic corrosion, coating cadmium over the base metal is preferred in these industries. Cadmium coatings are quite effective in protecting the base metal from rust or any other degrading property.
