Castle nuts, also known as slotted or castellated nuts, are specialised fasteners with slots cut into one end designed to accept a cotter pin or safety wire. This feature ensures secure locking, preventing the nut from rotating under vibration or torque.
Castle nuts are primarily used in automotive, machinery, and aerospace applications. They are crucial for maintaining safety and operational integrity in environments subject to high levels of vibration or dynamic loads. Their design ensures fastenings remain secure even in demanding conditions, providing reliable performance and safety.
Fabory offers castle nuts that conform to standards like DIN 935-1, DIN 937, DIN 979, ASME B18.2.2, BS 1768, and NEN 729. These nuts are available in steel and stainless steel (A2, A4) with surface treatments such as plain and zinc-plated. The sizes range from metric M4 to M80 and imperial sizes from 1/4 inch to 1 inch, catering to a various applications.
