Description
Hexagon Nut M20 DIN 934 A4-80 Acid-Resistant Stainless Steel
Hexagon Nut M20 DIN 934 A4-80 is a premium fastening component made from A4 (AISI 316) grade acid-resistant stainless steel. It is the ideal solution for installers who require maximum corrosion resistance in aggressive environments – including marine, chemical, and industrial settings.
Why choose A4-80 steel? The A4 (AISI 316) material contains molybdenum, which provides exceptional resistance to pitting and crevice corrosion – significantly outperforming standard A2 steel. The 80 strength class guarantees higher load capacity than the popular A2-70, resulting in safer and more durable connections under heavy loads.
When to choose A4-80 instead of 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 areas, swimming pools, and the chemical and food industries.
Compliance with the DIN 934 standard means a standardised hexagonal shape that allows easy tightening with a standard wrench. The nut is reusable and fits all M20 metric bolts with right-hand thread.
