This hex nut is made from A2 stainless steel and manufactured to DIN 934 standards. Rated at strength class 70—which translates to a minimum tensile strength of 700 MPa—it features metric threading. The COMBIFLON coating is a dry, solid, silver-colored topcoat that dramatically reduces the risk of thread galling in stainless steel while bringing the friction coefficient back to normal, more consistent levels. In a bolt-and-nut assembly, coating just the nut with COMBIFLON is enough to prevent galling. As an added benefit, the coating also helps minimize contact corrosion.
