Lapp Skindicht MR-M M25/M20 Brass Lock Nut, Nickel-Plated, 50 Pieces

The Lapp Skindicht MR-M is a professional-grade nickel-plated brass lock nut designed to facilitate thread reduction from M25 to M20 in electrical installations. This component is engineered to provide a secure and stable connection for cable glands, ensuring that electrical systems remain protected and mechanically sound. With its robust construction, it serves as a reliable solution for industrial environments where durability and precision are essential for cable management.

Advantages

The primary benefit of this nickel-plated brass lock nut is its exceptional mechanical strength and resistance to environmental factors, which ensures long-term reliability in demanding industrial settings. By allowing for a seamless transition between different thread sizes, it offers versatility in system design and installation. The high-quality material composition prevents corrosion and provides a secure fit that maintains the integrity of the cable gland assembly over time.

Suitable for

• Industrial electrical control panels
• Machinery and equipment manufacturing
• Automation and robotics systems
• Electrical distribution enclosures
• Cable management in harsh environments

When it may not be suitable

This component is specifically designed for metallic thread reduction and may not be compatible with plastic-only enclosures where excessive tightening could damage the housing. It is also not intended for use in high-vibration environments without appropriate locking washers or thread-locking compounds.

Key specifications

• Material: Nickel-plated brass
• Thread size: M25 (external) to M20 (internal)
• Quantity: 50 pieces per pack
• Application: Thread reduction for cable glands
• Durability: High mechanical stability

How to use

To install the Lapp Skindicht MR-M, first ensure that the M25 threaded hole or entry point is clean and free of debris. Screw the reduction nut into the M25 opening until it is firmly seated. Once the reduction is in place, the M20 cable gland can be threaded into the internal M20 opening of the lock nut. Tighten both connections using appropriate tools to ensure a secure and vibration-resistant fit, taking care not to overtighten the assembly.

What to consider before purchase

• Verify the thread size requirements of your existing enclosure and cable gland.
• Ensure the material compatibility with your specific industrial environment.
• Confirm that the quantity of 50 pieces meets your project requirements.

Usage recommendations

Always use calibrated tools to tighten the lock nut to prevent damage to the threads or the enclosure surface. Ensure that the cable gland is properly aligned before final tightening to maintain the IP rating of the installation.
