Roll Thread vs. Cut Thread

Note: Most of our Anchor bolts are roll threaded.

Roll threading an anchor bolt produces a stronger thread and weighs less than a cut threaded anchor bolt. The threads are stronger because roll threading is actually forming the threads and cold working the metal. It pushes the root of the thread down and the crest up. Rolled threads are clean and smooth and don’t create any waste in the form of shavings.

The material diameter of Rolled anchor bolts is normally about the same as the pitch size of the thread. The pitch is the midpoint between the bottom and the top of the thread. A 1” round A36 anchor bolt will measure about .910 diameter. We can provide cut thread bolts if you need them. Please specify if it is important what type of thread you get. Most of the time either cut thread or rolled thread will work equally for any anchor bolt project.
