Acorn Lock Nut

Acorn lock nuts are specialized fasteners designed with a domed top that covers the exposed bolt threads, protecting them from damage, corrosion, and accidental contact. The acorn shape not only enhances safety but also gives a clean, finished look to the assembly. These nuts are widely used in automotive, furniture, machinery, and decorative applications where both functionality and appearance matter.

A self locking acorn nut goes one step further by incorporating a built-in locking feature that resists loosening from vibration or movement. This makes it ideal for dynamic applications such as vehicle suspensions, machinery joints, and equipment subject to constant motion. The locking mechanism can be achieved through nylon inserts or deformed threads, providing a strong grip without the need for additional locking washers.

Both types of nuts are available in various materials, including stainless steel, brass, and carbon steel, with optional surface finishes like chrome plating or zinc coating for enhanced corrosion resistance.

By choosing acorn lock nuts or self locking acorn nuts, you ensure a secure, long-lasting, and visually appealing fastening solution. They combine safety, strength, and style—making them a popular choice for both industrial and decorative applications.

Acorn Lock Nuts and Self Locking Acorn Nuts – Safety Meets Style

Acorn lock nuts feature a closed-end dome design that shields bolt threads from environmental damage while preventing injury from exposed sharp ends. This design is particularly valued in automotive and decorative uses.

For high-vibration environments, self locking acorn nuts integrate a locking mechanism to maintain fastening integrity under constant movement. They are widely used in vehicles, industrial machines, and sports equipment.

Made from stainless steel, brass, or plated carbon steel, these nuts provide both durability and corrosion resistance. The polished dome shape also enhances the visual appeal of the finished assembly.

By combining strength, safety, and aesthetics, these nuts are a versatile solution for many fastening needs. Whether you require standard or locking versions, we can supply them in bulk with consistent quality.
