DIN 508-24-M22-10 hexagonal nut Z012416

DIN 508 castellated nut – reliable fastening in various applications

The DIN 508-24-M22-10 castellated nut is a fastening element widely used in machines, equipment, and steel structures. Its design, with a slot for a key, ensures convenient and secure assembly and disassembly, especially in hard-to-reach places. Manufactured according to the DIN 508 standard, it guarantees high quality and connection reliability.

Construction and materials

This nut is available in various material versions – carbon steel and stainless steel (AISI 304 and AISI 316Ti). The steel version undergoes heat treatment, which increases its tensile strength (classes 8 or 10). Stainless steel provides corrosion resistance, which is crucial in aggressive environments. This makes the nut suitable for both indoor and outdoor applications.

Applications and benefits

DIN 508 castellated nuts are commonly used for:

• Fastening structural elements: in machinery construction, industrial equipment, and steel structures.
• Connecting elements requiring frequent disassembly: e.g., in pipeline systems where regular maintenance or component replacement is necessary.
• Protection against loosening: the castellated slot allows the use of a tool to tighten and secure the nut against self-loosening during operation.
• Assembly of elements in hard-to-reach places: thanks to the possibility of using a castellated key, assembly is possible even where access is limited.

It is worth remembering that DIN 508 nuts of class 8 may also be available in a solid version (without a slot), which increases their strength and connection safety. In this case, the thread designation should be omitted when ordering.
