A corner key includes a heel and at least one leg extending from the heel defining a longitudinal axis. A nose is disposed along the longitudinal axis. The nose includes a first wedge area and an opposite second wedge area. The corner key further includes a bridge connecting the nose to the at least one leg. Upon insertion into a frame member, the nose substantially rotates to engage both the first wedge area and the second wedge area within the frame member and wedge the nose therein.
