Heavy Hex Nuts are slightly larger and thicker than finished hex nuts. There are numerous grades and the heavy pattern is typically used for large diameter and high strength bolts. These nuts offer adequate strength for many applications but this nut style does not work in some condition as it does not provide a “One Size fits all” solution. JF Engineering offers the best solution in supplying the variety of heavy hex nut having varieties of features:
If you are using the proper combination of fasteners that allows the reliable design even under heavy loads and extreme conditions.
