Abstract

An improved tilt latch bolt for a double-hung window with a groove or channel formed in either the biased or planar portion of the bolt nose for engaging a portion of the window frame when the window is under duress is disclosed herein. The grooves and channels define a depth of at least five thousandths of an inch (0.127 cm). The deformable cantilever, by virtue of being formed above, and extending over the channel, is resilient such that were a portion of the window jamb to clear the width of channel, the deformable cantilever provides a small degree of tolerance to capture the wayward window jamb before it inadvertently rotates out of the sash, for example in inclement weather conditions.
