All thread rod or fully threaded studs have two critical dimensions consisting of diameter and length. The length of shorter pieces of all thread rod (studs) can be measured in overall length (OAL) or “first to first”. First to first measures the stud from its first complete thread on one end to its first complete thread on the other end, eliminating the chamfers on the ends of the studs in the length measurement. Thread pitch can also vary from Unified National Coarse, to 8UN, to Unified National Fine depending on the specification.
