Nord Lock Combi Nuts.

What are Nord Lock Combi Nuts?

Nord Lock combi nuts are innovative, high-precision anti-vibration locking nuts designed to provide secure and reliable locking solutions in intensive applications.

These specialised nuts feature an integrated anti-vibration washer, which utilises a wedge-locking mechanism that ensures a robust hold even under severe vibrations and dynamic loads. This unique design of Nord Lock combi nuts distinguishes them from conventional nuts.

Additionally, the hexagonal drive type allows for easy installation and removal using standard socket sets, making them highly convenient for both assembly and maintenance tasks.

How Nord Lock Nuts Work

Nord Lock nuts excel in scenarios requiring exceptional locking performance, particularly in industries such as automotive, aerospace and heavy machinery.

The wedge-locking mechanism of these combi nuts is activated upon tightening; the design of the incorporated Nord Lock washer creates a cam effect that counters rotational movement. This ensures that the preload in the bolt remains consistent, safeguarding against self-loosening. This makes them an essential component in critical applications where failure is not an option.

The benefit of having the combination of nut and washer in one component simplifies installation and enhances safety, particularly in challenging environments like working at heights or in tight spaces. This integrated design reduces the number of parts, minimising the risk of dropping components during installation and ensuring a more secure and reliable connection. This convenience and reliability are crucial for maintaining safety and efficiency in such demanding scenarios.

Materials Nord Lock Combi Nuts Are Made From

Nord Lock nuts are manufactured from high-quality steel, chosen for its strength and durability. This makes them capable of withstanding significant tensile forces in tough conditions. The combined nut and washer feature a zinc flake coating for superior corrosion resistance against moisture, chemicals and salt, making them ideal for harsh environments.

Additionally, the washers feature a dry film lubricant for smoother installation and reduced galling risk. These nuts have excellent corrosion resistance, proven by their ability to withstand a minimum of 600 hours in an ISO 9227 salt spray test.

What Sizes of Nord Lock Combi Nuts are Available

Nord Lock combi nuts come in a range of sizes to accommodate various project applications, with thread sizes ranging from M6 (6mm) to M16 (16mm). This range of sizing options allows engineers and technicians to select the appropriate size for their specific requirements, ensuring optimal performance and reliability.

FAQs

Q: Can Nord Lock nuts be reused?

A: Nord Lock combi nuts can be reused. However, it is important to inspect them for any signs of wear or damage before reinstallation. The wedge-locking mechanism ensures that the washers retain their locking function even after multiple uses, but ensuring the integrity of the component is crucial for maintaining a secure and reliable connection.

Q: Are Nord Lock combi nuts suitable for high-temperature applications?

A: Nord Lock combi nuts are suitable for use in temperatures ranging from -50°C to 150°C. This range makes them ideal for various industrial applications, including those exposed to significant temperature variations. The locking function remains effective within this specified temperature range, ensuring reliable performance even in challenging conditions.

Q: How do Nord Lock combi nuts compare to traditional locking methods?

A: Nord Lock nuts offer superior locking performance compared to traditional methods such as our range of nylon-insert lock nuts or spring washers. The wedge-locking mechanism of the washer provides a consistent preload and resists loosening because of vibrations or dynamic loads. This makes them more reliable in critical applications where maintaining bolt tension is essential, reducing the risk of failures and maintenance needs.
