Helukabel KM MS M25 x 1.5 Brass Locknut

The Helukabel KM MS M25 x 1.5 brass locknut is a precision-engineered component designed for the secure fastening of cable glands in industrial electrical installations. Constructed from high-quality nickel-plated brass, this locknut provides exceptional mechanical strength and long-term durability, ensuring that cable entries remain firmly fixed within enclosures even in demanding environments.

Advantages

This locknut offers superior vibration resistance compared to plastic alternatives, making it an ideal choice for heavy-duty industrial applications where equipment stability is critical. The nickel-plated brass construction provides excellent corrosion resistance, ensuring a reliable electrical and mechanical connection over the lifespan of the installation. Its precise metric threading allows for smooth installation and a tight, secure fit that prevents loosening due to external mechanical stress.

Suitable for

• Securing cable glands in industrial control panels
• Electrical installations in machinery and automation systems
• Enclosures requiring high mechanical stability
• Environments where vibration resistance is necessary

When it may not be suitable

This locknut is not intended for use in environments where extreme chemical exposure might degrade nickel-plated brass, or in specialized applications requiring non-conductive materials. It is specifically designed for metric M25 x 1.5 threads and will not fit other thread sizes or standards.

Key specifications

• Material: Nickel-plated brass
• Thread type: Metric M25 x 1.5
• Application: Cable gland fastening
• Resistance: High mechanical stability and vibration resistance

How to use

To install the locknut, first insert the cable gland through the opening of the enclosure. Thread the locknut onto the gland from the inside of the enclosure. Tighten the locknut firmly using an appropriate spanner to ensure the gland is securely locked against the enclosure wall. Ensure that the threads are properly aligned before tightening to prevent cross-threading.

What to consider before purchase

• Verify that your cable gland and enclosure opening are compatible with the M25 x 1.5 metric thread standard.
• Ensure the material compatibility matches your specific environmental requirements.
• Check the available space inside the enclosure to accommodate the locknut profile.

Usage recommendations

For optimal performance and to maintain the integrity of the connection, ensure the locknut is tightened to the manufacturer's recommended torque. Regularly inspect the installation during routine maintenance to confirm that the connection remains secure and free from signs of mechanical wear.
