Well, I recently had a fastener that I thought was a torx head. Nope. Hex head then maybe. Nope.
It turns out that it was a "double square" head. I did discover that a number 2 square drive would remove it easily. I went onto McMaster Carr and sure enough, they sell Double Square driver bits.
Speaking of hand sanitizer.. I made my own with 91% alcohol. The first time my daughter used it in the truck she had to get out.... "Good God man, are you trying to kill me?" was her response. LOL
