Stainless Hex Nut
Stainless hex nuts to DIN 934 / ISO 4032. Match the stainless grade to the bolt — A2 nut with A2 bolt, A4 nut with A4 bolt. Mixing carbon steel and stainless creates galvanic corrosion potential.

Buyer Questions
Frequently asked questions
Why match stainless grade between bolt and nut?
Different grades have different galvanic potentials and slightly different mechanical properties. Mismatched grades are not an immediate failure mode but can lead to galvanic corrosion at the threaded joint over long service. Match A2 with A2 and A4 with A4.
