Stainless Steel Hex Nut 316 (A4)

A4-70 (AISI 316) hex nuts to DIN 934 / ISO 4032 — the chloride-resistant mating nut for A4 bolts and threaded rod.

Specify A4 nuts in marine, poolside, wastewater, and chemical service, always matched with A4 male fasteners: a mixed A2/A4 joint corrodes at the weaker component. Lubricate threads at assembly to avoid galling. Available metric sizes are in the table above.

Sold per piece with a 50–100 piece minimum order depending on size. Include sizes and quantities in your quote request together with the matching bolts or rod.
