I made a hex chisel of a common long nut, drilled a hex hole on a MDF board, and made a removable handle for hex nut.
Originally I designed this for my homemade tablesaw and its fence. And then I felt this might universally helpful for everybody. So I separate this.
Once I made this hex chisel, I can easily make hex nut handles anytime. So, this is simple and useful.
I hope this way of making helps many people.
