DIN 1587

DIN 1587 refers to a German standard (Deutsches Institut für Normung) that specifies the requirements for a type of nut called a "cap nut" or "acorn nut". Cap nuts are designed with a rounded, dome-shaped cap on one end, which covers the end of a threaded fastener (such as a bolt or screw). This cap serves multiple purposes, including protection from injury due to exposed sharp threads, preventing corrosion by covering the threads, and providing a more aesthetically pleasing appearance.

Cap nuts are typically made from various materials such as stainless steel, brass, or nylon and can be used in a wide range of applications. They are commonly used in the automotive, construction, and furniture industries. The DIN 1587 standard outlines the size, dimensions, materials, and other technical requirements for these cap nuts to ensure consistent quality and performance.

Uses of DIN 1587

1. Automotive industry: Cap nuts are used in various automotive applications to provide protection to exposed threads and enhance the appearance of vehicle components.
2. Construction: Cap nuts are used in the assembly of construction equipment, machinery, and structures to protect workers from injury due to exposed sharp threads and to prevent corrosion on threaded fasteners.
3. Furniture industry: Cap nuts are often used in the assembly of furniture, providing a clean, finished look by covering exposed threads. They also help protect the threads from damage and corrosion, ensuring a longer lifespan for the furniture.
4. Electronics and appliances: Cap nuts can be used in the assembly of electronic devices and appliances, protecting threads from damage and providing a more aesthetically pleasing appearance.
5. Playground equipment: Cap nuts are frequently used in the construction of playground equipment to cover sharp threads, reducing the risk of injury to children and providing a more polished appearance.
6. Marine applications: The use of stainless steel cap nuts in marine applications can help protect against corrosion caused by saltwater exposure.
7. General assembly: Cap nuts are used in various general assembly tasks where protection of threads, safety, and aesthetics are important considerations.
