Lapp Skindicht MR-M Brass Lock Nut M40 to M32

The Lapp Skindicht MR-M is a professional-grade brass lock nut designed to facilitate the transition between different thread sizes in industrial electrical installations. This high-quality reducer allows for the seamless integration of cable glands with smaller connection threads into larger existing threaded holes, specifically adapting an M40 opening to accommodate an M32 component. Engineered for reliability, this component ensures a secure and stable connection in demanding environments.

Advantages

Constructed from robust, silver-coloured brass, this lock nut offers exceptional mechanical stability and long-term durability. Its material composition provides superior resistance to corrosion, making it an ideal choice for harsh industrial settings where equipment integrity is paramount. The precision-engineered threads ensure a tight fit, minimizing the risk of vibration-induced loosening and maintaining the overall safety of the electrical system.

Suitable for

• Industrial electrical installations
• Transitioning between M40 and M32 thread sizes
• Securing cable glands in control cabinets
• Mechanical engineering and automation systems

This component may not be suitable for applications requiring non-metallic or plastic materials due to specific chemical resistance or weight requirements. It is also not intended for use in environments where brass is incompatible with the surrounding materials or where extreme electrical insulation properties are required beyond the capabilities of metal fittings.

Key specifications

• Material: Nickel-plated brass
• Thread size (external): M40
• Thread size (internal): M32
• Colour: Silver
• Application: Cable gland reduction

To install the Lapp Skindicht MR-M, first ensure that the existing M40 threaded hole is clean and free of debris. Insert the reducer into the opening and tighten it securely using an appropriate wrench to ensure a firm mechanical connection. Once the reducer is in place, the M32 cable gland can be threaded into the internal side of the lock nut, following the manufacturer's torque specifications for the gland itself.

What to consider before purchase

• Verify the thread size of your existing enclosure or housing
• Confirm the thread size of the cable gland being installed
• Check for environmental compatibility with brass materials
• Ensure sufficient space for the reducer profile

For optimal performance and safety, always ensure that the threads are properly aligned before tightening to prevent cross-threading. Regularly inspect the connection during routine maintenance to confirm that the assembly remains secure and free from environmental degradation.
