Heavy Hex Jam Nut

A heavy hex jam nut is an excellent choice for applications that require a heavy load capacity but require a shorter height. A heavy hex jam nut is slightly larger than a standard hex jam nut but slightly shorter than a standard heavy hex nut as well. They are often used as a secondary nut to ensure a standard hex nut is secured in place and will not loosen from vibrations; they ‘lock’ the hex nut in place for projects that require stability. The compact design allows them to fit in areas that can’t accommodate a second standard hex nut while offering greater hold due to the steel alloy composition.
