I got a light plastic awning from amazon. It only has 3.4 pounds. The size are 30"x40". Now I want to install it over the front door.
The package comes out a set of bolts(The size is marked as M10).
However I heard that this kind of bolt is permanently positioned. In other word, it can't easily removed. If the awning is damaged or I want to sell the property in the future, I have to uninstall the awning, then it becomes a problem.
So I am wondering is that possible to replace the bolts with other types which can be easily removed?
