Specification of Heavy Hex Nuts | Roll Fast
Heavy hex nuts are slightly larger and thicker than standard hex nuts. These nuts are first cut as per weight requirement and then the machining on both sides with the required height. There are numerous grades, and the heavy pattern is typically used for large-diameter and high-strength bolts. We do heat treatment on them in our factory using an advanced SQF-sealed quench heat treatment. See our chart to determine the compatible heavy hex nuts for a specific grade of bolt.
