Flat Round Screw OBO Bettermann FRSB M6x16 Fire Galvanized – M6 x 16mm corrosion-resistant fastener

Flat Round Screw OBO Bettermann FRSB M6x16 Fire Galvanized is a M6 x 16 mm fastener with a low-profile round head and fire-galvanized corrosion protection. It is designed for secure mechanical fixing in electrical and construction applications where a discreet head and long-term resistance to rust are required.

Advantages

The screw combines a standard M6 thread with a 16 mm length and a flat round head that reduces protrusion. Fire galvanization provides uniform corrosion resistance suitable for indoor and certain exposed environments. The design offers dependable mechanical strength for mounting brackets, conduits and fittings while maintaining a neat appearance.

Suitable for

• Mounting electrical brackets and cable clips
• Fixing conduits and pipe supports
• General sheet metal and light structural assemblies

How to use

Select a matching M6 nut or tapped thread and pre-drill or prepare the substrate according to material thickness. Position the screw through the component to be fastened, align the flat round head for minimal protrusion, and tighten with the appropriate screwdriver or driver bit until secure. Follow standard torque and safety practices for the material and application to avoid over-tightening.

Usage recommendations

For long-term corrosion resistance, use in well-drained or non-continuously wet environments and inspect fastenings periodically in harsher conditions. Match the screw length to material thickness so the threaded engagement is sufficient without excessive protrusion.
