What is a cap nut?

Use of cap nuts in bicycles

In bicycles, cap nuts are often used for securing components such as fenders, bike racks, and seat posts. They ensure a safe and neat finish of bolts and protect the threads from dirt and moisture. Additionally, cap nuts help cover sharp edges, providing extra safety while cycling. 

A cap nut is a type of nut with a closed end, which fully covers the thread of a bolt. This not only offers protection against dirt and moisture but also gives a tight and polished appearance to the connection. Cap nuts are widely used in the cycling world, automotive engineering, and furniture construction.
 

What types of cap nuts are there?

Cap nuts are available in various materials and designs:
•    Steel cap nuts: Strong and durable, often galvanized for extra rust resistance.
•    Stainless steel (SS) cap nuts: Ideal for outdoor applications due to their corrosion resistance.
•    Plastic cap nuts: Lightweight and suitable for applications where heavy loads are not required.
•    Self-locking cap nuts: For extra grip and safety, preventing loosening due to vibrations.
 

What to consider when buying cap nuts?

When choosing the right cap nut, you should consider:
•    Material: Choose steel for strength or SS for corrosion resistance.
•    Thread size: Ensure that the cap nut fits the bolt being used.
•    Application: For outdoor use, a stainless steel variant is recommended, while plastic is ideal for light applications.
•    Mounting method: Self-locking cap nuts provide extra security against loosening.
 

What is the difference between a regular nut and a cap nut?

The main difference lies in the finish:
