DIN 508-20-M16-8 hexagonal nut Z012410

DIN 508 castellated nut – reliable fastening in demanding applications

The DIN 508-20-M16-8 castellated nut is a fastening element widely used in industry, construction, and mechanical engineering. It is characterized by high strength and resistance to loads, guaranteeing the safety and durability of connections. Manufactured in accordance with the DIN 508 standard, it ensures compatibility with other fastening elements.

Design and application

The castellated nut, thanks to its special slot, allows for secure and reliable seating of the screw or stud. The castellated slot allows for the transfer of torque, which is particularly important in applications exposed to vibrations or dynamic loads. It is an ideal solution for connections requiring additional protection against loosening. Castellated nuts are used in:

• Agricultural machines and equipment
• Steel structures
• Transport equipment
• Equipment for production halls
• Installation of industrial plants

Material and strength

The nut is made of steel with a strength class of 8. This means that it is characterized by high resistance to tensile and static and dynamic loads. This strength translates into long-lasting and reliable operation in various operating conditions. A version made of stainless steel AISI 316Ti and AISI 304 is also available, which provides corrosion resistance and the possibility of use in an aggressive environment. It is worth remembering that class 8 nuts can also be supplied in a solid version, without a hole – in such a case, the thread size designation should be omitted when ordering.

Additional information regarding the properties of stainless steel and the strength of nuts can be found in the manufacturer's technical documentation (see page A26 and A20).
