It's so heart warming to see a whole nation so proud of one of their great inventions...a screw head.
I do really appreciate the square drive head but the torx is just as good and better in some cases.
RV manufacturers use the Square drive screw primarily for speed in installing.
Finding the tool here is easy, finding the screws is much more difficult.
And CW should be ashamed of itself it it didnt know what that screw was...I guarantee out in the shop there are lots of them and a whole bucket of the screws.
