Heavy Hex Nuts are larger-than-standard hex nuts specifically designed for high-strength structural bolting applications. Often referred to as heavy hexagon nuts or large hex nuts, they are commonly paired with heavy hex bolts and screws. These nuts feature increased thickness and wider across-flat dimensions, requiring greater torque during installation but delivering enhanced strength and stability to the joint.

Heavy hex nuts are available in both metric and imperial sizes, with threading options including UNC (Unified National Coarse), UNF (Unified National Fine), UN (Unified National Fixed), and ISO metric thread profiles. They are manufactured using a wide range of materials and grades, conforming to relevant ASTM standards and international specifications.
