What is the difference between 8.8 and 10.9 bolts?

I'm curious to understand the distinction between 8.8 and 10.9 bolts. Could you elaborate on the key differences in terms of their strength, applications, and any other pertinent factors that might influence the decision to use one over the other in various engineering or construction projects? Additionally, are there any specific industries or scenarios where one bolt type is preferred over the other?
