All threaded rod is available in different lengths depending on the material. For basic stainless such as 18-8 (304, ASTM A194 B8) or 316 (ASTM A194 B8M), 6′ and 12′ lengths are standard. On most other non ferrous materials, the lengths will vary. The mills that produce round bar in these materials usually ship variable lengths ranging from 10′ to 20′. Additionally, in the cut threading process, a few inches of thread is lost because it is needed to grip onto the bar. Lengths in our inventory will vary and some pieces may have a butt-end. We will cut all threaded rod to simplify handling and prevent damage in shipping. Our standard shipping tubes are designed to handle 3′ or 6′ pieces.

What is a Threaded Rod
A threaded rod is a long metal rod that is fully threaded with threads long its entire length. It does not have a head.
Check out our part’s diagram:
Thread Types
UNC Threads (Unified National Coarse threads): This thread type uses standard units and has fewer threads per inch. It is more tolerant to dirt & damage. It is used for for general purpose fastening.
UNF Threads (Unified National Fine Threads): This thread type uses standard units and has more threads per inch. It is better for more precise applications and higher strength.
ISO Metric Threads: This thread types uses metric units and offers but coarse & fine variants. The M coarse and M fine are the two designations.
ACME Threads: These are trapezoidal profile threads are thicker, stronger & provide a smoother motion. They are also more durable & resistant to wear.
Applications & Industries
High-temperature & High-Pressure Fastening (e.g., turbine systems & reactors)
Threaded rods secure flanges, pressure vessels, or components in extreme thermal and mechanical environments.
