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.

 

Heavy Hex Nut Standards and Specifications
The most popular Heavy Hex nut standard is the ASME B18.2.2 which covers the complete general and dimensional data for the various types of inch series square and hex nuts. Widely used ASTM standards that cover the Heavey Hex Nuts are:

 

ASTM A194
ASTM A563
Heavy Hex Nut Dimensions
Heavy hex nut dimensions basically consist of three specific dimensions as listed below:

 

Nut thickness (T)
Width across flats (F), and
Width across corners (C)
