Description
DIN 6923 M10 Flange Nut – A2 Stainless Steel for PV Installations
DIN 6923 M10 hexagon flange nut made of A2 stainless steel (1.4301, grade 304) — a component designed for safe and reliable connections in photovoltaic systems. The serrated flange design increases clamping force and prevents self-loosening caused by vibration, which is crucial when mounting roof hooks and mounting triangles to aluminium profiles.
Made from austenitic 1.4301 (A2) stainless steel, the nut offers exceptional corrosion resistance thanks to the addition of nickel to the alloy. The material is non-magnetic, flexible and resistant to stress — ideal for use in demanding weather conditions throughout the entire lifetime of the solar installation.
