ASTM A-193 All Thread Rod


All Thread Rod ASTM A193 B7 Cadmium Yellow

ASTM A-193 All Thread Rod is often sometimes referred to as “rod” or “redi-rods”.  They are fully threaded and are typically available in 12ft or 10ft lengths.   Threaded rod can come in a wide variety of alloys from carbon steel, hardened alloy steel, and even high nickel alloys such as Hastelloy, Monel, and stainless steels.  Threaded rod is often formed by roll threading, and often cut into smaller and custom sized lengths which are referred to studs or stud bolts.

Grade B7 is designed to mate with ASTM A194 Grade 2H Heavy Hex Nuts to help firmly fasten structures and objects together.  All thread rod comes with deeply grooved threads that were typically created through a process called roll threading. . It is the thread’s slope and depth in a rod that can add to or hinder the amount of flexibility you may need in the structure you are binding together. The count of Threads Per Inch (TPI) or the Thread Pitch can be used to accurately identified which is the best rod to use for a particular task.

Since the threads on a rod are finely polished, it is best not to pre-drill a hole before securing these rods in a structure. The threaded rods are used to build tension and should be directly installed in the material when possible to ensure their full strength is maintained.

The primary requirement when installing a threaded rod into wood, concrete, steel, or another material is to have the right length and enough thread on the rod to hold your pieces together and securely fasten them in with corresponding nuts.  Proper thread engagement is critical when it comes to saftey.

ASTM A-193 All Thread Rod is often used by electrical, heating, plumbing, and commercial and industrial construction assignments, all thread rod should not be substituted for a headed bolt or a headed anchor bolt but are meant for very strong structural junctions.
