Castle nut

The castle nut is shaped as a hexagon with additional locking elements resembling a crown.

The part comes in two design variants:

• slotted nut;
• castle nut.

Rigid locking at the installation point is achieved by installing a cotter pin. If required, a flat washer of a suitable size is placed under the nut.

Applications

Castle nuts are used in most industries, and especially widely in mechanical engineering.

When selecting a nut, note that the thread and size designations follow either the GOST or the German DIN standard.

During installation, the castle nut is positioned so that the holes in the bolts or studs align with the slotted elements of the nut. The connection can then be secured with a cotter pin.

Features

Nuts are made from various materials: brass alloys, carbon steel grades, stainless steel.

The protective coating improves the appearance of the nut and enhances its technical and performance characteristics, allowing the connection to be used under adverse environmental conditions.
