Yes, a drill blank is the way to go. I had to replace
a 7mm shear pin in my snowblower, and they don't make

tough, and don't cost much at all.

Bad idea to use a drill blank as a *shear* pin. It is supposed
to fail when there is an overload (think mechanical fuse).
Using a tougher higher tensile material is like putting a penny
behind the fuse in a fusebox.
