Nylon lock nuts or stop nuts, as they're also called, are economic and extremely effective. They have a nylon insert, or collar, which is smaller than the thread diameter. As the nylon insert lock nut is tightened, the collar deforms over the mating diameter, creating friction.
A jam nut is a low profile type of nut, typically half as tall as a standard nut. It is commonly used as a type of locknut, where it is "jammed" up against a standard nut to lock the two in place. It is also used in situations where a standard nut would not fit.
Almost every new car nowadays comes with a locking wheel nut (sometimes referred to as a wheel lug nut or an alloy wheel nut), and it's a very important part of your car because they prevent a criminal from taking your alloy wheels off your car and stealing them.
