Mushroom head screw for cable tray systems

Mushroom head screw FRS 8x16 F 5.6 is a fastening element designed for the assembly of cable tray systems, as well as in many other installation applications. Made of steel, with hot-dip galvanized surface, it provides corrosion resistance and connection durability. Supplied with a washer and a hexagonal nut, which facilitates and speeds up assembly.

Design and application

This screw is characterized by a mushroom head with a square socket, allowing for convenient installation with a 13 mm socket wrench. Metric thread with a diameter of 8 mm ensures a secure and stable connection. It is primarily used in cable and wire fastening systems, but due to its versatility, it can also be used in other structures requiring a solid and durable connection of steel elements.

Safety and compliance with standards

FRS screws from OBO Bettermann meet strict safety standards, including system for maintaining operational efficiency E90 according to DIN 4102-12. This means that connections made using these screws maintain their functionality for at least 90 minutes in the event of a fire, which is crucial for ensuring safety in buildings. Hot-dip galvanizing further increases corrosion resistance, guaranteeing long-term reliability even in harsh environmental conditions.
