ATR or All thread rods are generally referred to as redi-rod, fully threaded rod, continuously threaded rod and TFL rod. The rod is used largely for general purpose fastening. We supply a range of grades & materials.

Stock

The stock of all thread rod available at Baseline Bolt is manufactured domestically and includes a range of physical and chemical test reports. All grades of all thread rod available with us can be shipped in varying lengths including 6’, 10’, or 12’ or can be cut to length before shipping. All thread which is cut to length will be chamfered, stamped or rather color coded to identify grade and galvanize if necessary. While stainless steel grades aren’t listed here, orders placed for stainless steel grades can be readily supplied by us.

* ASTM A36 is a steel grade, not a fastener specification. Technically, all thread rod made from A36 steel should be ordered to a fastener specification such as A307 Grade A, A307 Grade B, or F1554 Grade 36. The appropriate fastener specification will depend on the application. However, Baseline Bolt stocks all thread rod manufactured from A36 steel and can certify it as such upon request. Learn more about ordering fasteners to A36 in this FAQ.
