46-22 12-Inch Steel Combination Square

I have had a Stanley 12" combination square with a brass thumb wheel for 40 years. I decided to buy a second one a few years ago as the numbers were getting hard to read on the ruler. The new one has a plastic thumb wheel, and it has stripped in a very short time. Stanley is sending me a new one with a plastic thumb screw, that will probably strip. It would cost Stanley less to provide a brass thumb screw with new squares rather than shipping me a new one under warranty,and keep the Stanley quality reputation. Also of note, a competitor's combination square comes with a brass thumb screw, and notes it on the packaging. So I would assume this is a known issue that can easily be fixed by Stanley. .

Except for the plastic nut, this seemed to be ok. Is there an option to get a brass version of the nut like the old Stanley combination square had? It's a shameful design error.
