Non-reversing fasteners include a bolt having a groove defined along the thread, and a nut having a biased tooth disposed in an internal pocket. When the nut is threaded onto the bolt, the biased tooth does not engage the groove. When the nut is reversed off the bolt, the biased tooth stays in an extended position and engages the groove, preventing it from reversing. A tool positions on the nut and moves the biased tooth from the extended position to a retracted position, allowing the nut to reverse off the bolt. The tool can be another nut having a magnet for moving the tooth from the extended to the retracted position. A reverse arrangement can have a bolt with a biased tooth and a nut having a groove. A tool in the form of a magnetized rod can fit into an axial bore in the bolt to move the tooth.
