The 116 M32 LGR PS nut from OBO Bettermann is a component for the secure fastening of screw connections in electrical installations. It is particularly used in conjunction with cable glands and protective conduits, where a stable and durable connection is required. The product is made of polystyrene and is available in light grey (RAL 7035), making it suitable for use in industrial and commercial facilities. The nut complies with DIN 46319 and features a metric thread according to IEC 423, ensuring universal applicability in standard applications.

Nut is the central component that, together with a screw and a threaded nut, creates a secure connection. In electrical installations, it is used, for example, to fasten cable glands to metal conduits or other mounted components. The use of polystyrene as the material provides good electrical insulation, allowing the nut to be used in environments with increased insulation requirements. The light grey colour (RAL 7035) enables visual coordination with other components in the installation.

Technology explained clearly: The nut is placed on the opposite side of the screw to support tightening and ensure even preload. The metric thread according to IEC 423 allows compatibility with standard screws and nuts commonly used in electrical and building technology. DIN 46319 specifies the geometric and functional requirements for nuts to ensure uniform quality and compatibility. Due to the material properties of polystyrene, special care must be taken during installation: the nut must only be tightened moderately to avoid stress cracking. This is an important consideration when using plastic components in mechanically stressed connections.

Compatibility and accessories: The nut is designed for use with cable glands and protective conduits, particularly in systems requiring secure and durable fastening. It is compatible with standard screws and nuts featuring the metric thread M32. Use in combination with other components from the OBO Bettermann range, such as protective conduits or cable glands, is possible as long as the thread requirements match. The nut is not supplied as part of a pre-assembled set, but as an individual component.

Installation and mounting: During installation, care must be taken to tighten the nut only moderately to avoid material fractures due to stress cracking. The use of appropriate tools, such as a suitable wrench, is recommended to achieve even preload. The nut is placed on the side opposite the screw to stabilise the connection. Mounting typically occurs on metallic or solid substrates where secure fastening is required.

Operational advantages: Using the 116 M32 LGR PS nut provides a reliable and durable connection in electrical installations. The electrical insulation provided by the polystyrene material protects against short circuits and increases operational safety. Compliance with DIN 46319 ensures high quality and compatibility with other components. The light grey colour (RAL 7035) allows for visual harmonisation with other components in the installation. The specific mounting instruction for moderate tightening protects the component from mechanical overload and extends the connection's service life.

Applications: The nut is suitable for use in electrical installations, particularly in industrial and commercial facilities. It is frequently used in conjunction with cable glands and protective conduits to securely fasten cables and wiring. Use in environments with increased insulation requirements is possible, as polystyrene offers good electrical insulation. The nut is not intended for use in environments with high mechanical loads or high temperatures, as polystyrene may lose its strength under such conditions.

Functions and equipment in detail: The nut features a metric thread M32, manufactured according to IEC 423. DIN 46319 ensures the nut meets the required geometric and functional specifications. The polystyrene material provides good electrical insulation and is suitable for use in electrical installations. The light grey colour (RAL 7035) enables visual coordination with other components. The specific mounting instruction for moderate tightening protects the component from stress cracking.

Manufacturer and type: The product is manufactured by OBO Bettermann and carries the manufacturer's number 2049554. The type 116 M32 LGR PS refers to the specific version of the nut with metric thread M32, light grey colour (RAL 7035), and polystyrene as the material. The nut is part of the range of installation components and is categorised under protective conduits / cable glands / rubber sleeves / cable clamps.
