Description
Hexagon Nut M16 DIN 934 A4-80 Acid-Resistant Stainless Steel
Hexagon Nut M16 DIN 934 A4-80 is a premium fastening component made from A4 grade (AISI 316) 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? 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 high load.
When should you 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 zones, 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 M16 metric bolts with a right-hand thread.
