If you ever come across panel screws that have been heavily painted, soft metal, rusted, or just plane worn out..... this tool is a savior.
I've found the cheapest price was from Brown Tool
We also have this guy named "He Man" running around aviation maintenance. This guy is in corporate aviation as well as commercial. He works for all the airlines and all the business jet operations world wide!!!! He Man loves to over torque everything..... including screws. I seem to see a lot of his previous work. Dragging out El Brutus or a screw knocker always adds that extra "specialness" to a job.
