All thread rod (ATR) is a common, readily available fastener that is used in multiple construction applications. Rods are continuously threaded from one end to the other and are frequently referred to as fully threaded rods, redi rod, TFL rod (Thread Full Length), and a variety of other names and acronyms. Rods are typically stocked and sold in 3′, 6’, 10’ and 12’ lengths, or they can be chopped to a specific length. All thread rod that is cut to shorter lengths are often referred to as studs or fully threaded studs.
The most common, readily available all thread rod is ASTM A307 Grade A and A193 Grade B7. These two grades are readily available in the marketplace all over the country and are mass produced. However, several other grades of all thread rod are common in the marketplace and nonstandard size and grade combinations can be manufactured for its many applications.
