Aluminium fasteners are highly prized for their extreme light weight, but raw aluminium threads are highly susceptible to "galling"—a process where friction causes the threads to cold-weld and seize together, destroying the fastener. IG Quality Industries solves this by anodizing aluminium screws, bolts, and washers. The anodizing process transforms the soft thread surface into a hard, crystalline oxide, acting as a dry lubricant that allows for smooth torquing without galling. Available in a wide spectrum of colors, these anodized fasteners are heavily used in the RC, automotive, and aerospace industries for weight reduction, absolute rust-prevention, and aesthetic color-coordination of complex assemblies.
