Flat Round Screw OBO Bettermann FRSB M6x12 Fire Galvanized – M6 x 12 mm, fire-rated, galvanized

Flat round screw OBO Bettermann FRSB M6x12 with fire-galvanized finish, thread size M6 and length 12 mm. The screw is intended for secure fastening in installations that require both fire performance and corrosion resistance, such as electrical and mechanical assemblies, mounting brackets, fixtures and conduit supports.

Advantages

The FRSB M6x12 combines a flat round head profile with a fully threaded M6 shank to provide a flush or low-profile head where required. The fire-galvanized surface improves corrosion protection and supports use in applications with fire-safety requirements. The screw offers consistent dimensional accuracy and is compatible with standard M6 threaded components.

Suitable for

• Electrical installations and mounting of junction boxes
• Fixing mounting brackets and cable management systems
• Mechanical assemblies requiring M6 fasteners
• Conduit supports and light structural joints

How to use

Select a matching M6 nut or threaded component and position the parts to be fastened.

Ensure threads engage fully and check that the head sits flush or at the intended low profile after tightening.

Usage recommendations

Use the FRSB M6x12 in environments where both fire-resistance of the coating and corrosion protection are needed; avoid use in applications requiring stainless steel fasteners or where higher mechanical strength grades are specified.
