High Tensile UNF [fine thread] black bolts.

Generally speaking fine threads are used on chassis components and suspension parts on Hot Rods, Street Machines, race cars and motor cycles because they are less likely to work their way loose due to vibration. A course thread, for example like UNC thread is prone to the nut or bolt loosening over time with vibration or shock loads. The fine pitch of a UNF bolt means there is a flatter plain for which the thread to pull against the bolt and nut therefore making it extremely hard for them to work their way apart when torque down properly.
