It defines the dimensions, materials, and mechanical properties for hexagon lock nuts that are primarily used in machine construction and vehicle engineering.
The standard covers nuts in sizes from M3 up to M100, with normal and fine thread versions.
The nuts are designed to prevent unintentional loosening when subjected to vibration or shock loads. They incorporate a nylon insert or other locking feature to achieve this.
DIN 1587 nuts are commonly made from steel, stainless steel, or other corrosion-resistant materials depending on the application requirements.
The standard specifies tests and quality control measures to ensure the nuts meet the performance and safety criteria.
DIN 1587 is widely used across Europe and internationally as a benchmark for reliable, self-locking hexagon nuts in industrial machinery, vehicles, and equipment.
