STAINLESS STEEL AND OTHER SPECIAL ALLOY STEEL
Lubrication should be used to prevent two separate possible issues:
GALLING - The problem is often referred to as 'thread galling' or another description used has been 'cold welding', quite simply the two fastener components become unexpectedly locked together as if they had been welded. As stainless steel is easily prone to galling, special additives are used to prevent galling.
