Scope DIN 463 is widely used in mechanical engineering, construction and manufacturing industries for good fastening of structural elements, prevents self-unscrewing of threaded connections under dynamic impact and vibration.
Material stainless steel.
Coating Zinc (Plated) protects against corrosion if fasteners are intended to be used in aggressive environments.
