Abstract
A fastener with shaving inhibitor for fastening a material such as a metal sheeting panel to a substrate such as metal or wood. The fastener has a notch angled leftwardly with respect to an axis of the fastener, the notch having a first end and a second end, a leading face and a trailing face, each face having outer edges and a common edge at their intersection. At least one of the leading and trailing faces may be substantially planar but may have other shapes, such as concave. Leftwardly angled notch with faces having outer edges may attract and then cut shavings formed from material being installed, thereby reducing the quantity and/or length of shavings, prolonging the life of the material or the structure to which the material is fastened.
