Description
M16 Hexagon Nut DIN 934 – A2-70 Stainless Steel for PV Installations

This M16 hexagon nut is made of A2 stainless steel (1.4301) in accordance with the DIN 934 standard — a reliable fastening component designed for professional photovoltaic installations and structures exposed to weather conditions. The A2-70 marking visible on the component confirms the strength class and material grade, making identification on site easier. Austenitic stainless steel provides exceptional corrosion resistance thanks to the nickel content in the alloy, while its non-magnetic properties and high elasticity ensure durable connections even in demanding environmental conditions.

- Easy identification on site thanks to clear strength class marking on the nut
- A proven solution for roof-mounted installations, ground-mounted PV farms and carport structures
- Suitable for all climate zones — retains full mechanical properties regardless of environmental conditions
