This hex nut is manufactured to DIN 934 standards in plain steel—raw steel with no coating or surface treatment. While the material itself is strong, it offers little inherent protection against corrosion. The nut features metric threading and is rated at strength class |10|. Please note: class |10| nuts are rated according to DIN 267-4 and have a lower load capacity than class 10 nuts rated to ISO 898-2. Mechanical overloading can cause the threads on either the nut or bolt to strip.
