## Long description

The Lapp Skindicht MR-M is a professional-grade brass reduction lock nut designed to facilitate the transition between different thread sizes in electrical installations. This component allows for a seamless conversion from an M20 thread to an M12 thread, ensuring compatibility between various cable glands and enclosure ports. Constructed from high-quality brass with a durable nickel-plated finish, this lock nut provides robust mechanical stability and reliable protection against corrosion in demanding industrial environments.
Advantages
The primary benefit of this reduction lock nut is its ability to adapt existing equipment to different cable gland sizes without the need for complex modifications. The nickel-plated brass construction ensures long-term durability and resistance to environmental factors, making it suitable for both indoor and outdoor electrical applications. Its precise threading ensures a secure and vibration-resistant connection, which is essential for maintaining the integrity of electrical systems in automation and engineering projects.
Suitable for
Adapting M20 enclosure ports to accommodate M12 cable glands
Industrial automation and control cabinet installations
Electrical engineering projects requiring thread size transitions
Environments where corrosion resistance and mechanical strength are required
This product may not be suitable for applications requiring non-metallic or plastic components, such as those involving specific chemical exposures where brass might be reactive. It is also not intended for use in high-pressure hydraulic systems or applications where the thread pitch does not match standard metric specifications.
Key specifications
Material: Nickel-plated brass
Thread size conversion: M20 (external) to M12 (internal)
Quantity: 100 pieces per pack
Finish: Corrosion-resistant nickel plating
To use the Lapp Skindicht MR-M, simply thread the reduction nut into the existing M20 port of your enclosure or junction box. Once securely tightened, the M12 internal thread is ready to accept the corresponding M12 cable gland. Ensure that the threads are properly aligned before tightening to prevent cross-threading and to maintain the mechanical integrity of the connection.
What to consider before purchase
Verify that the enclosure port is M20 and the cable gland is M12
Ensure the environment is compatible with nickel-plated brass
Confirm the quantity required for your specific project scale
For optimal performance, ensure that the lock nut is tightened to the manufacturer's recommended torque specifications. Regular inspections are advised in high-vibration environments to ensure the connection remains secure over time.
