Yet another Wingnut (1/4" or 6mm)

Yet another wing nut. This one is for 1/4" bolts, with a 7/16" head. It should play okay with a 6mm bolt too. It was made as part of a couple other projects I'm working on, but it's such a nice wing nut, I figured it could use it's own thing.

The photo shows a feather board, this is just for the wing nut on the feather board.
