Also known as:
Thinner than "regular" nuts, Hex Jam Nuts derive their name from being "jammed" against another nut to prevent it from coming loose. To lock regular nuts, install Jam Nuts first so the regular nut will be on the outside and thus carry the full bolt load. See our Hex Jam Nut Dimensions reference chart.
