ABSTRACT OF THE DISCLOSURE A two-way fastener which is adapted for joining at least two members in, electively, either a reusable position or a non-reusable position includes an elongate shank, a head member which is integral with an upper portion of the shank, an elongate rail member integral with and substantially parallel to the shank, the rail member having a substantially tee-shaped cross section, a plurality of non-reusable resilient teeth attached to a side of the shank which is opposite the rail member and a plurality of reusable teeth attached to second and third sides of the shank. The non-reusable teeth are angled toward the head member at a first angle, and the reusable teeth are angled toward the head member at a second angle which is less than the first angle. When inserted into a slotted member so that the two sets of reusable teeth engage the sides of the slot, the device acts as a reusable fastener. When inserted so that the elongate rail member and non-reusable teeth contact edges of the slot, the device acts as a non-reusable fastener. An additional function of the rail member is than it constrains the fastener against rotation with respect to a slot in which it is inserted.
