Hex Jam Nut, Thin Pattern, Left Hand Thread

Left hand threaded nuts, also known as reverse nuts, are not suited for standard bolts. They are installed by spinning counter-clockwise and are used with left-hand threaded bolts, screws, and rods. This reverse threading is most often used to fasten machinery with a rotary blade such as bicycle pedals, turnbuckles, or sometimes even a car's wheels. The reverse threading helps prevent loosening gradually under the torque of these applications.
