Afraid not. Inagine a regular 6 sided bolt head. It uses a regular socket. Now, make it with 3 sides instead of 6. I need a 3 sided socket wrench. Perhaps a thin walled 6 point would work
I finally got the screws out. Here are pictures of what I used. It was dumb luck that I thought to try that screwdriver handle. The screws were very tight so I carefully used the wrench for more torque.
