Abstract

There has been an increasing need for a better steel insert or bushing between aluminum and steel bolts in the last few years with the rapid growth of the aircraft and missile industries. The steel insert or bushing threaded internally and externally, by increasing the area of contact with the aluminum raises the strength of the bolt fastening combination approximately 300 per cent or causes a 125,000 PSI bolt to fail rather than 40,000 PSI aluminum to fail. In addition, galling and seizing are practically eliminated. A bolt installed and removed just a few times in aluminum is likely to tear out the aluminum thread due to the inherent gulling and seizing tendency.
