Question, I ordered the bracket to install my cell phone on my sterring wheel. See pic below. As you can see in my second pic, I need to remove the two bottom screws with an hex tool. I attempted with a regular hex but the screw is too hard to take it out with the small L shaped hex tool. Any other ideaa how to remove the bottom two screws. Do I need a power tool to remove this screws? Also when I remove the two bottom screws will nothing come apart, correct?
