## Long 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.

Type: Flat round screw (FRSB)

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.

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.
