Surface Finish

Threaded rods that are rolled instead of cut are smoother and have less surface imperfections that may cause possible failure in severe service applications. Thread rolling dies impart smooth burnished roots and flanks to threads. Rolled threads are free from tears or tool marks typically found in cut threads. Those surface imperfections contribute to fatigue failure, and may lead to catastrophic failure.
