What are Heavy Hex Nuts?
Heavy hex nuts are six-sided (hexagonal) internally threaded fasteners and larger versions of common/standard hex nuts. They are widely used for structural applications and because of this, heavy hex nuts are also known as structural nuts. Hex-heavy nuts are used for high-strength threaded fastening with large diameters. They are thicker and wider than standard hex nuts.

Similar to all other nuts, the heavy hex nuts are also used along with other fasteners mainly with a bolt to secure two or more materials together. To provide a long-lasting experience, heavy hex nuts are produced in zinc, plain, stainless steel, and galvanized finishes.

Paired with heavy hex bolts, these types of nuts are most common in construction and engineering applications. Hex-heavy nuts are available in various grades and selected based on the application.
