The 116 M20 LGR PA counter nut from OBO Bettermann is a component for the secure fastening of cable glands and protective conduits in electrical and installation engineering. It is particularly used in conjunction with screw-type cable glands to ensure a firm and durable connection. The product is standardized according to DIN 46319 and features a metric thread in accordance with IEC 423, ensuring compatibility with standardized installation components. The counter nut is made of polyamide (PA) and is available in light grey (RAL 7035), making it suitable for use in industrial and commercial installations.

Counter nut is the central component used in combination with a screw-type cable gland or cable gland closure to stabilize the fastening. It is mounted on the opposite side of the gland to transmit the clamping force and ensure a secure connection. The use of counter nuts is particularly required in installations subject to high mechanical stress or in areas with increased requirements for mounting quality.

Metric thread according to IEC 423 enables universal use with other components based on the same standard. The thread profile is standardized and ensures a secure and tight connection without additional adjustments. The DIN 46319 standard defines the geometric and functional requirements for counter nuts used in electrical installation and machine construction.

Polyamide (PA) as a material offers high mechanical strength, resistance to wear, and chemical resistance. It is particularly suitable for use in environments with increased mechanical stress or in areas with low thermal load. The light grey colour (RAL 7035) is a standardized colour used in many industrial installations to achieve visual harmonization of installation components.

The counter nut is typically mounted in conjunction with cable glands or protective conduits to increase fastening security.

Compatibility is ensured with all components featuring a metric thread according to IEC 423 and complying with DIN 46319. The counter nut is specifically designed for use with screw-type cable glands in electrical and installation engineering.

Applications include electrical installations in industry, commerce, and building technology, particularly for securing cable glands to machines, devices, or in enclosures. The counter nut serves as a mechanical support to distribute clamping force and prevent loose connections. Its use is especially beneficial when mounting components are insufficiently stable or additional securing is required.

Operational advantages include easy installation, high mechanical stability, and compliance with standards. The counter nut ensures a durable connection that remains secure even under mechanical stress. The use of polyamide ensures long service life and resistance to wear. The light grey colour allows for visual integration into existing installations.
