Castle nuts, also known as castellated nuts or slotted nuts, are specialized fasteners designed to prevent loosening in various applications. Featuring distinct notches or slots along their circumference, castle nuts are commonly paired with a cotter pin to secure screws and bolts effectively. We offer a wide range of castle nuts in different sizes and materials to meet your specific fastening needs, ensuring reliable performance in both low torque and high-stress environments.

What are castle nuts used for?
Castle nuts are used to secure bolts and screws in applications where loosening is required. They are commonly used in automotive, mechanical and structural projects to ensure fasteners remain tight under vibration and dynamic loads.
How are castle nuts prevented from coming loose?
Castle nuts have grooves or notches that match the slotted pin. Once the slotted pin is passed through the notch and bent in place, the nut is locked in place, preventing it from turning and loosening over time.
What is the difference between a castle nut and a standard nut?
The castle nut has grooves or notches in its circumference, so it can be secured by cotter pins. Standard nuts do not have these features, they rely solely on tightening torque to stay in place and are therefore more likely to loosen under vibration.
Can castle nuts be reused?
While castle nuts can be reused, the cotter pin must be replaced each time the nut is removed and reinstalled. The notch or notch on the nut remains intact and can be reused as long as a new cotter pin is available.
What are the options for Castle Nuts?
Castle Nuts are available in a variety of materials, including stainless steel, carbon steel and galvanized. The choice of material depends on the application requirements, such as corrosion resistance and strength.
