    The Allstar Performance ALL16081-10 is a set of 10 fine thread mechanical lock nuts sized 5/16-24. Each nut is made from steel with a zinc oxide finish and uses a deformed thread section rather than a nylon insert to resist loosening from vibration. The 5/16-24 thread is a fine (UNF) pitch, matching fine thread bolts and studs of the same size. Because there is no nylon insert, this nut can be used in higher-temperature applications where a nylon insert nut is not suitable.
