A hinge assembly for casement windows is shown and described. The hinge assembly includes a slide block for connection to the sash arm that includes a reinforcing plate that extends downward before extending upward and around the flange of the track overhang. A larger undercut portion is provided beneath the reinforcing plate for added clearance between the slide block and fasteners used to secure the track to the window sill. The hinge assembly also includes a pivot base which is pivotally connected to the shorter tie bar or toggle link. The position of the pivot base with respect to the track can be adjusted as a means for compensating for sash sag. An additional hole is also provided to provide new anchorage in the case of a sash sag adjustment or additional anchorage for use in high wind areas. The pivot base also includes a quick disconnect retainer disposed beneath the pivot base and between the pivot base and the track and thereby hidden from plain view. The short tie bar or toggle link is riveted to a pivot pin thereby eliminating the need for any rivet connection to the track. The pivot pin extends downward from the tie bar through the pivot base and is retained by the retainer which is disposed beneath the pivot base.
