Jam Nut
Jam nuts are a low-profile hex nut used as a locknut to prevent vibration from loosening a bolted joint. Before nuts were developed with “self-locking” capabilities, two jam nuts would be tightened against each other so that nuts won’t loosen over time. The first nut is held with a wrench while the second nut is tightened or “jammed” against the first to lock both nuts in place. • Available with both left-handed and right-handed threads • Low-profile design makes this nut ideal for low clearance applications • Overall height is similar to a standard hex nut when jam nuts are doubled
