Heavy Hex Jam Nuts are thinner than a standard heavy hex nut but have the same dimensions across the flats and corners. Heavy Hex Jam Nuts shorter in height than a standard hex nut, hex jam nuts have the same measurements across the widths and flats. They can be used to run up against a hex nut to lock the hex nut in place or as a leveling nut, among other uses. 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.
