SS 201 Bolts and Nuts FAQs
Answers to common customer inquiries regarding SS 201 fasteners.
Are UNS N02201 Nut covered by ASTM F593 or ISO 3506?

- SS 201 supplied per ASTM A276, A240, or A493
- Standard dimensions per DIN 933 or ISO 4014
Why are SS 201 bolts cheaper than 304?
- SS 201 has 3.5–5.5% nickel content
- SS 304 has 8–10.5% nickel content
- Lower nickel directly reduces material cost
Can I use AISI 201 Studs outdoors in a coastal city?
- Not recommended for coastal or salt-air environments
- Lower chromium and nickel reduce corrosion resistance
- Use SS 304 or 316 for outdoor coastal service instead
Do ASTM A193 Type 201 Hex Nuts stick to a magnet?
- Yes, mild magnetism from cold heading is normal
- Also seen in cold-headed SS 304 fasteners
- Use PMI testing or MTC for accurate grade verification
What certification comes with an SUS 201 Threaded Rod order?
