Stainless Steel Threaded Rods FAQs

What is a stainless steel threaded rod?2025-07-11T01:59:56-04:00

Threaded rod, also known as ‘all‑thread’ rod, is a continuous, fully threaded fastener used in joining, bracing, and structural applications. Our stainless steel threaded rod resists corrosion, making it ideal for marine, outdoor, and industrial use.

What sizes of stainless steel threaded rods do you carry?2026-06-04T10:17:26-04:00

We offer both imperial and metric stainless steel threaded rods from stock:

  • Imperial sizes: 1/4″-20 up to 1″-8, available in full-length rods or cut-to-size.
  • Metric sizes: M3 to M30, conforming to international standards and ideal for global projects and OEM assemblies.

Not seeing the size you need? Contact our team directly, and we’ll confirm availability or arrange a custom cut.

Can I order custom-cut stainless steel threaded rod?2026-06-04T10:17:43-04:00

Absolutely. We provide cut-to-length services for both 304 stainless steel threaded rod and 316 stainless steel threaded rod. When requesting a quote, simply specify:

  • Required length
  • Diameter
  • Thread pitch

We’ll cut to your exact specifications.

Are stainless steel threaded rods suitable for structural applications?2026-06-04T10:18:13-04:00

Yes. Our stainless steel threaded rod is manufactured to meet ASTM and ISO standards and is commonly used in:

  • Anchoring systems
  • Bracing and framing
  • Load-bearing structures
  • Marine and moisture-exposed assemblies

Both 304 and 316 grades are suitable for structural use, with 316 recommended where the assembly will be exposed to moisture or corrosive conditions.

Do you carry stainless steel nuts and washers for use with threaded rod?2026-06-04T10:18:29-04:00

Yes. We offer a full selection of stainless steel nuts, washers, and companion hardware designed to match our threaded rod in both 304 and 316 grades. We recommend using matching-grade hardware throughout:

  • Pairing 304 rod with 304 nuts and washers
  • Pairing 316 rod with 316 nuts and washers

This eliminates the risk of galvanic corrosion at the connection point.

What’s the difference between a 304 and 316 stainless steel threaded rod?2026-06-04T10:18:52-04:00

Stainless steel threaded rod is most commonly manufactured in 18-8 stainless steel (304 grade) or 316 stainless steel:

  • 18-8 (Type 304): The most commonly used grade due to its excellent corrosion resistance and high durability. It contains 18% chromium and 8% nickel, which improves its anti-rust properties.
  • 316 Stainless Steel: Often referred to as marine grade, it includes additional molybdenum, which increases its resistance to saltwater corrosion, making it ideal for marine environments or coastal applications.

Both grades are non-magnetic in their annealed state, but slight magnetism may occur after cold-working (e.g., threading or machining).
