Heavy Hexagon Nuts

Heavy Hexagon Nuts 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.
JF Engg  Offers Heavy Hex Nuts in Stainless Steel, Nickel Alloys, Carbon Steel, Alloy Steel, High Tensile alloy Steel, Non-ferrous materials like bronze, copper, aluminum, silicon bronze, titanium etc. We manufacture these high/heavy hex nuts as per DIN 5587 Standard, ISO 4033 Standard.
