Frequently Asked Questions
What is the difference between A2 and A4 class screws?
A2 (AISI 304) – universal stainless steel for most environments. A4 (AISI 316) – with molybdenum, better resistant to chlorides; recommended for marine and chemical conditions.
Are stainless steel screws compatible with metric thread system nuts?
Yes, DIN standard screws and nuts are compatible with each other according to metric thread systems (M3–M24).
