Nord Lock Washers

Fasteners like screws, bolts, and nuts are essential in manufacturing, construction, and assembly. However, they also face challenges such as loosening, leading to severe accidents. To address this issue, Nord-Lock Group developed the Nord Lock Washer. This type of lock washer is known for preventing bolts and screws from loosening during various applications. In this blog post, we’ll discuss Nord Lock Washer’s properties, composition, and uses.

What is Nord Lock Washer?

Nord-Lock’s washers are wedge-locking washers designed to secure bolted joints prone to vibration or dynamic loads. They use a unique pair of washers that create a positive lock. The first is a right-hand washer with radial teeth, while the second is turned in the opposite direction and has a set of matching teeth. Together, they create a wedge effect under the bolt head or nut that locks the fastener in place.

Nord Lock Washers Properties 

One of the main properties of Nord Lock Washers is that they secure bolted joints through tension instead of friction. This means the bolted joint remains secure even with extreme vibrations or dynamic loads. Additionally, the Nord Lock Washer is reusable and doesn’t damage the joint’s surface, making it a cost-effective option.

Nord Lock Washer Composition 

Nord Lock Washers use high-grade materials like carbon steel, stainless steel, and aluminium. These materials provide high corrosion resistance, strength, and a long service life. The company also innovatively designed its washers to fit various nut and bolt sizes, making them versatile in many industrial applications.

Uses of Nord Lock Washer

Nord Lock Washer is widely used in various applications such as transportation, power generation, general engineering, and petrochemicals. It is suitable for critical joints vital to safety and requires long-term reliability. Additionally, it is a cost-effective solution that can be easily installed and removed without special tools or skills.

Advantages of Nord Lock Washer

Nord Lock Washer offers significant advantages compared to other types of lock washers. Firstly, the wedge-locking design ensures a secure, vibration-proof connection, ensuring safety and reliability. Secondly, the Nord Lock Washer doesn’t require special installation, disassembly, or maintenance tools, making it easy to install and remove. Finally, Nord Lock Washer’s cost-effective solution helps reduce maintenance downtime and improve overall productivity.


In summary, the Nord Lock Washer is a unique invention that secures bolted joints and addresses the issue of loosening, especially in extreme conditions. It is composed of high-grade materials and is widely used in various industries, including transportation, petrochemicals, power generation, and general engineering. Its wedge-locking design ensures a secure, vibration-free, cost-effective solution for all industrial applications.
