A barrel nut is a female fastener used to bolt individual pieces of an assembly together without having an exposed nut on one of the work-piece faces. The barrel nut consists of a short, straight length of round bar with a perpendicular, threaded hole through its center. To install the nut, a hole is drilled, typically from a hidden surface, on a workpiece into which the nut fits. Another hole is then drilled into the workpiece to correspond with the position of the nuts’ threaded opening. This allows a second workpiece to be bolted to the first without any nut being visible on its face, a useful feature in aesthetically-sensitive applications such as furniture making.
