Heavy Hex Nuts
Heavy Hex Nuts A563 A194 F594
Heavy hex nuts are slightly larger and thicker than standard (finished) hex nuts. There are numerous grades and the heavy pattern is typically used for large diameter and high strength bolts. See our nut compatibility chart to determine the compatible heavy hex nut(s) for a specific grade of bolt. Since hot-dip galvanizing typically adds 2.2 to 5 mils of thickness to the threaded portion of a fastener, galvanized heavy hex nuts are tapped oversize to compensate for the corrosion resistant coating on the bolts.
Diameters: 3/8″ – 2-3/4″
Origin: Domestic and import
Finish: Plain and hot-dip galvanized
Grades: A563 (grades A, C, and DH), A194 grade 2H
