DIN 439A Thin Chamfered Hex Jam Nut with fine thread by Material, Finish and Size

Hex Jam Nuts have a lower profile than a standard hex nut but have the same dimension across the flats and corners. A hex jam nut can be threaded onto a bolt and run tight against a standard nut which will lock the nut in place and prevent it from backing off. Thus hex jam nuts may sometimes be used as locking nuts.
