Abstract
A self-locking threaded fastener that can be driven using conventional driving tools. The threaded fastener includes a fastener body and a locking band. The body includes a) a threaded portion and an unthreaded portion and b) an aperture extending radially from the unthreaded portion. The locking band includes a curved portion within the unthreaded portion of the fastener body and a tang extending into the aperture to limit angular movement of the tang with respect to the body. The curved portion terminates at an end having a range of radial movement with respect to the fastener body. When the threaded fastener is turned in a loosening direction, the locking band inhibit loosening of the threaded fastener.
