A tilt-latch (10) is adapted for releasably securing a pivotable sash window (12) disposed within opposed guide rails (16) on a master frame (14) of a window sash assembly (11). The sash window 12 comprises a top sash rail (20), a base (22) and two stiles (24,26) connected together at their extremities. The tilt-latch 10 comprises a housing (42) adapted to be supported by the top rail (20). The housing (42) has an outward end opening (44) and a pair of sidewalls (56,58). A latch bolt (46) is disposed within the housing (42) and has a nose adapted for engaging a respective one of the guide rails (16). The sidewalls (56,58) each have a first segment (80,82) and a second segment (84,86). The first segment (80,82) has a lesser thickness t.sub.1 than the second segment 84,86 providing a gap (g.sub.1,g.sub.2)between each sidewall (56,58) and the latch bolt (46). The first segments (80,82) are flexible to a flexed position during and upon installation wherein the first segments (80,82) do not contact the latch bolt (46), thereby allowing the latch bolt (46) to be retracted or extended through the outward end opening (44) without being obstructed by the sidewalls (56,58).
