Neverfriction® is an alternative to Zinc-Phosphating. This special coating is designed specifically for high strength fasteners used in a lubricated environment like internal engine or transmission applications. The coating process does not pit the surface of the fasteners so fatigue life is extended. This special coating provides for very consistent torque-tension performance, when tested according to ISO 16047.
