Product information

Description

Flat Round Screw OBO Bettermann FRSB M6x20 Fire Galvanized is a metal fastening screw with an M6 metric thread and 20 mm length, intended for installations where fire performance and corrosion resistance are required. The fire-galvanized finish increases protection against corrosion while maintaining standardized dimensions for compatibility with common electrical, mechanical and construction components.

Advantages

The FRSB screw combines a standardized M6×20 size with a flat round head for a low-profile appearance and stable seating. Fire-galvanized coating improves corrosion resistance in demanding environments. As a factory-standard fastener from obo bettermann (MPN 6406203, EAN 4012196199990), it ensures dimensional consistency and ease of replacement.

Suitable for

  • Securing electrical components and cable trays
  • Fastening mechanical parts in equipment assemblies
  • Construction connections requiring fire-rated fasteners
  • General installation work by electricians and technicians

Key specifications

  • Brand: obo bettermann
  • Manufacturer part number (MPN): 6406203
  • EAN: 4012196199990
  • Type: Flat round screw (FRSB)
  • Thread: M6
  • Length: 20 mm
  • Finish: Fire-galvanized (feuerverzinkt)

How to use

Select a compatible M6 threaded hole or use an M6 nut and position the flat round head so it sits flush or low-profile against the mounting surface. Tighten with the appropriate tool to the torque recommended for M6 fasteners in your application, avoiding over-tightening that could deform the head or strip threads. Use screws of the same specification for uniform fastening and documented fire-rated assemblies.

Usage recommendations

Verify material compatibility and required torque values for the specific installation. For exposed or corrosive environments consider additional protective measures. Replace damaged or corroded screws to maintain fire performance and mechanical integrity.
