Anti-seize Compound

Written by Jerry Ratzlaff. Posted in Fastener

An anti-seize compound is used on the threads of fasteners in some applications.  The purpose of the compound depends upon the application.  It can prevent galling of mating surfaces - such compounds are frequently used with stainiless steel fasteners to prevent this effect from occurring. In some applications it is used to improve corrosion resistance to allow the parts to be subsequently dis-assembled.  It can also provide a barrier to water penetration since the threads are sealed by use of the compound.
