Description
Hexagon Nut M12 DIN 934 A4-80 Acid-Resistant Stainless Steel
Hexagon Nut M12 DIN 934 A4-80 is a premium fastening component made from A4 (AISI 316) grade acid-resistant stainless steel. The ideal solution for installers who need maximum corrosion resistance in aggressive environments – including marine, chemical and industrial settings.
Why choose A4-80 steel? A4 (AISI 316) material contains molybdenum, which provides exceptional resistance to pitting and crevice corrosion – significantly outperforming standard A2 steel. Strength class 80 guarantees higher load capacity than the popular A2-70, resulting in safer and more durable connections under heavy loads.
When to choose A4-80 over A2-70? A4 steel is essential wherever there is contact with seawater, chlorides, acids or other aggressive agents. It is the standard choice for photovoltaic installations in coastal zones, swimming pools, the chemical industry and the food industry.
Compliance with the DIN 934 standard means a standardised hexagonal shape that allows for easy tightening with a standard wrench. The nut is reusable and fits all M12 metric screws with right-hand threads.
