    The Allstar Performance ALL16075-10 is a set of 10 fine thread thin nylon insert lock nuts sized 5/8-18. Each nut is made from steel with a zinc oxide finish and uses a nylon insert in the top of the nut to grip the mating thread and resist loosening from vibration. The 5/8-18 thread is a fine (UNF) pitch, matching fine thread bolts and studs of the same size. The thin profile has a reduced hex height compared to a standard nylon insert nut.
