Which method is least likely to secure door window glass to its frame?

The least likely method to secure door window glass to its frame is the use of screws. While screws can provide a strong connection in many applications, they may not be the best choice for attaching glass to a frame. This is primarily because screws can create stress points and potential cracking of the glass, especially if not installed with care or if the glass expands and contracts with temperature changes. Additionally, screws may not provide a continuous, evenly distributed holding force around the perimeter of the glass, which is crucial for maintaining its integrity and preventing rattling or loosening over time.

In contrast, bolts, rivets, and adhesives are more commonly used methods for securing glass. Bolts and rivets can provide a strong mechanical connection without the risk of compromising the glass structure, as they are designed to handle the load and stresses involved. Adhesives create a continuous bond that helps distribute stress evenly and securely holds the glass in position, making them particularly effective in automotive applications where vibration and movement are factors. These methods help to ensure the glass remains securely in place and can withstand the various forces encountered during vehicle operation.
