## Long description

The Helukabel 90177 is a high-quality brass lock nut engineered for secure and reliable fastening in diverse electrical installations. Designed with a standard M20 x 1.5 thread, this component provides essential mechanical stability for cable glands and various threaded connections. Its robust construction ensures that once tightened, the connection remains firm and resistant to vibrations, maintaining the integrity of your electrical systems over time.
Advantages
The primary advantage of this lock nut is its durable brass construction, which offers superior mechanical strength and excellent resistance to corrosion. The galvanic nickel-coated finish further enhances its longevity, protecting the component from environmental factors and wear. This makes it an ideal choice for demanding industrial environments where reliability and long-term performance are critical requirements for maintaining safe electrical infrastructure.
Suitable for
Securing cable glands in electrical enclosures
Fastening threaded components in industrial machinery
Commercial electrical installations requiring vibration resistance
Applications where corrosion resistance is necessary
When it may not be suitable
This lock nut is specifically designed for M20 x 1.5 metric threads and will not fit connections with different thread sizes or types, such as PG or NPT threads. Additionally, it may not be appropriate for environments involving extreme chemical exposure where specialized stainless steel or plastic materials might be required instead of nickel-coated brass.
Key specifications
Thread size: M20 x 1.5
Material: Galvanic nickel-coated brass
Type: Lock nut
Color: Brass/Metallic
How to use
To install the Helukabel 90177, slide the lock nut onto the threaded portion of your cable gland or connector. Ensure the threads are properly aligned to prevent cross-threading. Tighten the nut firmly against the enclosure wall or the mounting surface using an appropriate wrench. Ensure the connection is sufficiently tight to prevent loosening due to vibration, but avoid excessive force that could damage the threads or the enclosure material.
What to consider before purchase
Verify that your cable gland or threaded port is compatible with the M20 x 1.5 metric standard.
Ensure the material compatibility matches your existing installation environment.
Check the available space around the mounting point to ensure there is enough clearance to use a wrench for tightening.
Usage recommendations
For optimal performance and to prevent loosening in high-vibration environments, ensure the mating surfaces are clean and free of debris before installation. Regularly inspect the connection during routine maintenance to confirm the nut remains securely fastened.
