Helukabel 94263 M25 Polyamide Lock Nut, Grey, 100 Pieces

The Helukabel M25 Polyamide Lock Nut is a professional-grade fastening component designed to provide secure and stable installation for cable glands in various electrical and industrial environments. Manufactured from high-quality, durable polyamide, this lock nut offers excellent mechanical strength and resistance to environmental factors, ensuring that your cable entries remain firmly in place. The grey-colored finish provides a clean, professional appearance suitable for standard control cabinets and machinery housings.

Advantages

This lock nut features a specialized design with a collar that creates a larger sealing area, significantly improving the stability of the connection. The inclusion of this collar simplifies the installation process, especially when using an additional O-ring to achieve a higher degree of ingress protection. Its polyamide construction is inherently resistant to corrosion and chemical exposure, making it a reliable choice for long-term use in demanding industrial settings where vibration or mechanical stress might otherwise compromise standard fasteners.

Suitable for

• Securing cable glands in electrical enclosures
• Industrial machinery and automation systems
• Control cabinet wiring and distribution boards
• Projects requiring corrosion-resistant fastening solutions

When it may not be suitable

This polyamide lock nut is not intended for high-temperature environments that exceed the thermal limits of standard plastic materials. It should also be avoided in applications involving extreme mechanical impact or high-pressure steam cleaning where metal alternatives might be required for structural integrity.

Key specifications

• Thread size: M25
• Material: Polyamide
• Color: Grey
• Quantity: 100 pieces per pack
• Design: Counternut with collar

How to use

To install the lock nut, thread it onto the cable gland after the gland has been inserted through the panel or enclosure wall. Tighten the nut firmly against the inner surface of the housing to ensure the cable gland is locked securely in position. If an O-ring is being used for enhanced sealing, ensure it is properly seated between the gland collar and the enclosure surface before tightening the lock nut to compress the seal effectively.

What to consider before purchase

• Verify that the M25 thread size matches your specific cable gland and enclosure hole diameter.
• Ensure the material properties of polyamide are compatible with your operating environment.
• Consider the total number of connection points to ensure the 100-piece pack meets your project requirements.

Usage recommendations

For optimal performance and ingress protection, always ensure the mating surfaces are clean and free of debris before tightening. When using an additional O-ring, do not overtighten the nut, as this may deform the seal and reduce its effectiveness.
