The 116 M16 LGR PS nut from OBO Bettermann is a component for the secure fastening of screw connections in electrical installations. It is particularly used in the area of cable glands and for mounting protective conduits, where a stable and damage-free 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 installations. The nut complies with DIN 46319 and features a metric thread according to IEC 423, enabling universal use with standard screws and nuts.

Nut is the central term for this component, which serves as a counterpart to the screw to ensure a secure connection. The use of polystyrene as the material provides good electrical insulation and low weight, although it requires special care during installation. Due to the risk of stress cracking, which can occur with excessive tightening, only a moderate tightening torque is recommended. This is particularly important to avoid material fractures or connection failure, especially under repeated loading or in environments with mechanical vibrations.

Protection rating and thread are key technical features. The metric thread according to IEC 423 allows compatibility with standard screws and nuts, increasing compatibility with existing installations. DIN 46319 defines the geometric and functional requirements for nuts, ensuring uniform quality and interchangeability. The light grey colour (RAL 7035) serves for visual distinction and is often specified in industrial environments where clear identification of components is important.

Compatibility and accessories: The nut is designed for use in cable glands and protective conduits, particularly in combination with products requiring a metric thread. It is typically used in conjunction with screws and nuts to ensure secure fastening. Use in electrical installations requires adherence to installation instructions, especially the recommendation for moderate tightening, to avoid material damage.

Installation and mounting is done by simply screwing onto the corresponding screw. The nut acts as a bearing surface to securely fix the screw. Since the material is polystyrene, overloading must be avoided. Therefore, mounting should be done with appropriate tools and with attention to the recommended moderate tightening force. Over-tightening can cause cracks or breakage, impairing the functionality of the connection.

Operational advantages include easy handling, high insulation performance, and standardisation according to DIN 46319. The use of polystyrene ensures low weight and good electrical properties, which is particularly beneficial in installations with high safety requirements. The light grey colour supports visual identification and facilitates maintenance and inspection of the installation.

The nut is not part of a complex system, but a single component serving as a standard part in electrical and mechanical installations. It is used exclusively as a single unit in combination with other screw and fastening elements.

Technology explained simply: The nut serves as a bearing surface for screws to enable a secure connection. The metric thread according to IEC 423 ensures compatibility with standard screws. DIN 46319 sets the technical requirements to ensure uniform quality. The polystyrene material provides insulation, but requires special care during installation to avoid stress cracking.

Applications include electrical installation, particularly for securing cable glands, protective conduits, and other components requiring a secure mechanical connection. The light grey colour (RAL 7035) makes it suitable for industrial applications where clear visual distinction of components is important.

Functions and equipment in detail: The nut is made of polystyrene, enabling high electrical insulation and low weight. Its shape and thread comply with DIN 46319 and IEC 423, ensuring interchangeability and compatibility. The standard colour is light grey (RAL 7035). Mounting should be done with moderate tightening force to avoid material fractures.

Compatibility and accessories: The nut is designed for use with metric screws and nuts. It is used in cable glands and protective conduits where secure fastening is required.

Operational advantages: The nut offers easy mounting, high insulation performance, and standardisation. The use of polystyrene ensures low weight and good electrical properties. The light grey colour facilitates visual identification and maintenance.

Installation and mounting: Mounting is done by screwing onto the corresponding screw. The tightening force must be moderate to avoid stress cracking in the polystyrene. Using an appropriate tool is recommended to ensure even force distribution.
