Also known as castellated nuts, castle nuts are particularly useful for locking certain items in place on a project when you don’t want to use special locking nuts and bolts. A castle nut is easy to use because you can thread it without using a wrench initially. These nuts earn the name “castle” from their slotted heads, which resemble a castle parapet. Although you might wonder what these types of nuts could possibly be used for, they are probably used in items you see or use every day.
Bicycles
One of the most common uses for these types of nuts is with wheel bearings. As such, you can easily find them in use on bicycles. These nuts help to hold a wheel onto an axle. They are particularly useful because, as long as they are secured with a cotter pin, they will typically stay in place even when the wheel is moving and causing vibration. Regular nuts may have a tendency to unscrew over time due to vibration.
Cars
Since these nuts are often used with wheel bearings, it is also normal to come across them on the wheels of cars. In fact, if you have ever had to change a flat tire, you may have had to remove a castle nut before getting the damaged tire off and putting your spare on.
Trains
Trains also have plenty of wheels, which is why it is not uncommon to find a castle nut in use somewhere along a train’s many axles.
A Nut of All Trades
Castle nuts are useful when you need the power of a locking nut without the permanent commitment. As long as the castellated nut is secured with a cotter pin, it is not likely to move due to movement of the machine or vibration. It can also be used over and over again. The next time you are in need of a locking nut, especially if it is to secure a wheel bearing, consider the benefits of a castellated nut.
