Is it possible to use "hang on" as a meaning of catching something tightly?

"Hang on" cannot be used to mean to catch something lightly. It is primarily used to mean to hold or clutch something tightly, like grabbing someone's shirt, or to wait a little while, like in this video here. Ex: He hung on to the back of his father's shirt. Ex: Hang on a minute. I'll be right back!
