RAIL ANCHORING SPIKE
An improved rail anchoring spike that includes barbs is used for fastening metal to ties. The spike includes a head having one or more flanges and a stand-off extending axially from the flange(s). The spike includes a shank extending axially from the stand-off to form a tapered tip. The shank is adapted to engage dense material of the tie by a combination of threads and barbs on the shank. The threads are generally parallel and extend over a threaded portion of the shank. The shank includes a plurality of barbs positioned in a lower half of the threaded portion. Each barb is positioned between a pair of threads. Each barb is configured to minimize damage to fibers of the tie during installation of the spike as the fibers relax behind, and engage with, a barbed end. This prevents movement of the spike over time despite deterioration of the tie.
