Scope DIN 982 is used in mechanical engineering, construction, warehousing equipment, lifting equipment, agricultural machinery, tools, etc.
Material high-strength structural alloy steel. High strength class 10 allows the use of nuts with high-load connections.
Coating Zinc (Plated) protects against corrosion if you plan to use fasteners in aggressive conditions.
