The nut 116 M25 LGR PS from OBO Bettermann is a component for the secure fastening of screw connections in electrical and mechanical installations. It is particularly used in the area of cable glands and during the mounting of protective conduits, where a stable and durable connection is required. The product complies with standard DIN 46319 and features a metric thread according to IEC 423, ensuring universal usability in standard applications. The nut is finished in light grey (RAL 7035), making it suitable for use in both indoor and outdoor environments, especially in installations requiring visual harmonization of components.

Nut is the central term for this product, serving as the counterpart to the screw to ensure a secure connection. It is typically used in combination with screw cable entries, protective conduits, or other threaded components. The nut is screwed onto the screw to transfer tension to the connected component and enable a secure fastening.

Technology explained clearly

The nut is made of polystyrene, a plastic known for its mechanical strength and chemical resistance. Due to the material properties, special care is required during installation: polystyrene is prone to stress cracking, so the nut must only be tightened moderately. This prevents cracks from forming in the material, which could compromise the functionality and safety of the connection. Therefore, installation is carried out with moderate torque to maintain the mechanical integrity of the plastic.

Compatibility and accessories

The nut is designed for applications using metric threads according to IEC 423. It is therefore compatible with standard screw connections in the electrical and installation industry. Typical use includes combination with protective conduits, cable glands, or other threaded components. The light grey colour (RAL 7035) allows for visual coordination with other components in the installation, especially in industrial or technical environments.

Installation and mounting

Installation is performed by screwing the nut onto the corresponding screw, with strict adherence to the instruction to tighten only moderately. This is especially important when used in cable glands or for securing protective conduits, where the nut acts as the counterpart to the screw. The use of tools such as screwdrivers or wrenches is common, but the specified tightening torque must be observed to avoid material damage.

Advantages in operation

The nut provides a reliable fastening solution, distinguished by its standardization according to DIN 46319 and IEC 423. The use of polystyrene ensures good electrical insulation and chemical resistance, making it suitable for a wide range of applications. The light grey colour supports visual integration into existing installations. The clear instruction to tighten moderately ensures a safe and durable installation, increasing the service life of the connection.

Areas of application

The nut is used in electrical installations, for mounting protective conduits, cable glands, and other components connected via metric threads. It is particularly found in industrial plants, building technology, and during the installation of control panels. Its compliance with standards and material selection make it a reliable component in professional applications.

Functions and equipment in detail

The nut features a metric thread standardized according to IEC 423 and complies with DIN 46319. The polystyrene material offers high mechanical strength and electrical insulation. The light grey colour (RAL 7035) is suitable for visual coordination in installations. Installation is carried out with moderate torque to avoid stress cracking in the plastic. The nut is not a tool but a passive component used for fastening.
