A larger version of the commonly used finish hex nut, the heavy hex nut is used for large diameter and high strength threaded fastening. Hex Nuts are ideal for use in structural applications and cell tower modifications. The heavy hex nut, like all other nuts, are used with other fasteners ? typically a bolt ? to secure two materials together. Heavy hex nuts come in zinc, plain, stainless steel and galvanized finishes to provide long lasting durability.
