Are the bolts and/or internal threads lubricated?
If they say, “no,” suggest they try lubricating the bolts and/or internal threads with one of the lubricants listed earlier in the article. If this eliminates the galling, you might want to batch lubricate the remainder of the order to eliminate the extra work of applying lubricant at the point of assembly. In applications where galling is a repetitive problem, it is advisable to supply the fasteners with pre-applied lubrication to eliminate future problems.
