Heavy Hex Jam Nuts, Grade 2, Plain Finish

Heavy Jam Nut

Also known as:  

Heavy Half Height Nuts, Hex Heavy Thin Nuts

Thinner than "regular" hex nuts, Jam Nuts derive their name from being "jammed" against another nut to prevent it from coming loose. Heavy Jam Nuts offer the same width (and bearing surface) as heavy hex nuts, but are shorter in height. To lock regular nuts, install Jam Nuts first so the regular nut will be on the outside and thus carry the full bolt load.
