Description
Hexagon Nut M14 DIN 934 A4-80 Acid-Resistant Stainless Steel
Hexagon Nut M14 DIN 934 A4-80 is a premium fastening component made from A4 (AISI 316) grade acid-resistant stainless steel. An ideal solution for installers who require maximum resistance to corrosion 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-bearing capacity than the popular A2-70, resulting in safer and more durable connections under heavy load.
When to choose A4-80 instead of A2-70? A4 steel is essential wherever there is contact with seawater, chlorides, acids or other aggressive substances. 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 for easy tightening with a standard wrench. The nut is reusable and fits all metric M14 bolts with a right-hand thread.
